Aquarium hoods

Unless you purchased your home aquarium as an all-in-one kit which already has one, you will likely want to look into an aquarium hood for your set up. Even if you did get one in a kit, you may be interested in upgrading to a nicer style. The hood can serve several purposes for your aquarium set up.

First, the hood provides a finished look. It encloses the top of the aquarium so that items do not accidentally fall into the tank. Very often, the hood has a light source to illuminate the aquarium, providing simulated sunlight for aquarium plants and the fish, or just providing light in order to view the tank easier.

The hood also helps to keep the water from evaporating too rapidly by keeping the top covered and not exposed to the air. A hood will also help protect the water from air-borne contaminants and dust, some of which could be harmful to the fish. Also, a closed top will keep fish from leaping to a premature death, as some species are more prone than others to jumping out of the water; the hoods helps protect them and your investment in them.

When exploring hoods, you will consider the material that it is made out of. The simplest hoods are made from clear glass or plastic and simply cover the top of the tank. There is often two pieces to the hood connected by a plastic strip that serves as a hinge so you can lift one side to feed and clean the tank. With this set up you could rest a tube light on the non-moving side of the hood, but of course the parts are exposed and it does not have a finished look.

Wooden hoods can be quite elegant and made to match many decors. Wood and water often do not get along well together, so wooden hoods need to be treated to be water resistant. Plastic hoods are most common because they are durable and inexpensive.

When selecting a hood be sure to watch that it will fit your tank. Some hoods are designed to go on aquariums from certain companies and may not fit all models of tank.

Aquarium Stands, What Are the Options and Considerations?

So, you have decided to set up a home aquarium. But there is so much to consider before “diving” in. You can find many suggestions at the essential advice page. Here, we are going to focus on your aquarium stand.

When you first start out, you may only have a small aquarium that you set on some pre-existing piece of furniture. This can work fine, but there are several cautions. Aquaria need a lot of supporting equipment, such as fish food, nets, testing kits, and such. And there can be a lot of hoses and wires running to the tank for filters, heaters, and lights. It is not long before you might wish for a system to contain all this stuff. Not to mention, there are always little bits of water that splash out of the tank, say when filling it or cleaning, and you do not want that water getting on nice furniture. It can easily get under the tank and cause a lot of damage while going unnoticed.

The cure for this is a dedicated aquarium stand. There are several common styles you can buy, and like many other things, the nicer they are the more expensive they tend to be.

Regardless of which stand you end of going with, keep a couple of things in mind. First, the stand should be set up level. If the stand is off level, the water in the tank will sit unevenly in the aquarium. Aside from maybe looking a bit funny, the uneven water pressure could cause your tank to crack and break. Secondly, remember that when your tank is full of water it will be very heavy. Water weighs from 8 to 8.5 pounds per gallon, which means a large 55 gallon aquarium can weigh in at 470 pounds. Plus, you then add fish, pumps, rocks or aquarium gravel, and you soon have a very heavy house-hold component.

The most basic stand is a simple welded iron affair, often made out of painted angle iron. They tend to be the least expensive style, are sturdy and very functional. However, they are not particularly attractive. Prices range from $20 – $60 depending upon the size. You could drape this stand with a material cover to make it a bit more attractive.

You can buy special open shelving systems designed for aquaria. Usually, the top shelf is sized correctly for the size of aquarium you have, and there are open shelves below to store your equipment. This style of stand is less “industrial” looking than a simple welded stand. They range in price from about $60 – $150.

Moving up the “niceness” scale would be a closed cabinet, made out of compressed fiber board and often powder coated to make it more water resistant. This style is really just an enclosed version of the open shelf style, but it can be nice to close the doors on the equipment and supplies stored on the shelving. Prices generally start around $120 for this type.

Like any kind of cabinetry, you can get really nice cabinets made out of hard wood and finished with a nice finish. Understandably, the price is much higher, but they look really nice too. You can often get a matching top as well, that sits over the top of the tank and covers the hood and light system, giving a neat, finished look. These nicer cabinets start at $200 and go up from there depending upon size.

You could consider making your own aquarium stand if you have any carpentry skills. A simple closed cabinet style with simple doors would not be hard to make. Just remember to frame it with plenty of vertical supports to hold the tank weight, at least one support in front and back for every 24 inches of aquarium length. Also, use at least a ¾ inch plywood for the top.

A nice aquarium stand is a critical part of your aquarium set up, so give it some forethought, and get the best system you can.

Essential advice for starting a home aquarium

My granddaughter came to me yesterday and asked me to get her an aquarium. Before I could make such a promise I wanted to investigate what all was involved in setting up a fish tank.

As part of my investigation I decide that I need to review my knowledge and see what new advances the “experts” could teach me about the care of fish. I took my clip board and set out.

One of my first observations was the change in the sources of tropical fish. Years ago when I was keeping tropical fish there were many places to acquire small pets and fish. There was a time when many variety and dry goods stores, also known as five and dimes, had fish. The small stores have been taken over by today’s larger mini-marts, many of which do not have the personnel to care for live animals.

Today, fish can only be obtained from dedicated pet and pet supply stores. Some of these stores have general pet supplies, and a few specialize in fish and aquaria.

I visited three shops in my local area to get a feel for how knowledgeable the employees are. Two of the stores were general pet supply stores and one emphasized the aquarium. In all the shops the employees were eager to assist me, but of course the employee at the specialty store was much more helpful. The specialty shop not only knew about the fish and the equipment that I would need, she was eager to teach me how to set up a tank so that I would become a successful aquarist. Included in her advice was information about the various fish and how to pick fish that would result in a balanced community tank.

Basic items for a home aquarium:

  • Aquarium
  • Aquarium Stand
  • Hood/Light
  • Filter System
  • Filter Media
  • Aquarium Gravel
  • Heater
  • Thermometer
  • Fish Food
  • Supplemental Food
  • Bio-Boost
  • Gravel Cleaner
  • Books
  • Salts and water conditioner

Before any fish are purchased there should be some thought as to where the fish tank will be placed. The location of the tank will influence the size of tank to buy. Fish tanks can be purchased in 2.5 gallons to 150 gallons and larger. Even larger tanks can be special ordered or full wall aquaria can be installed but large fish tanks are probably not for beginners.

One important fact to consider when setting up an aquarium is the weight of a tank once it is set up. The water, aquarium gravel, aquarium hood, a filtration system, and all the cords necessary to operate the accessories could add up to a lot of weight. A five gallon tank set up can have a total weight of 45 lbs or more.   The home aquarist most often purchases a 55 gallon tank. An estimated weight for a 55 gallon fish tank would be about 500 pounds. Five hundred pounds of glass and water will require a very sturdy stable aquarium stand.

The size of the tank will influence the number of fish you should keep. The usual rule of thumb is one fish per gallon of water. This rule can be stretched in either direction depending on the breed of fish you select, and if you have a large fish tank. The larger the adult fish, the fewer fish per gallon. One of the factors that could have an influence on the number of fish kept in one tank is how frequently the tank will be cleaned. A crowded tank will need to be cleaned and filtered more often to prevent the pH of the water from rising too rapidly.

You can also get fish tanks in shapes other than rectangular. If you want to consider an aquarium of a unique shape be aware of the pros and cons. A multi-sided slender tank can add interest in the final effect of a display and show off the fish in a different way. However, it might complicate the cleaning of the tank as well as add expense for special equipment to set it up and to maintain.

Don’t forget that an electrical outlet should be somewhere near the proposed set up site.  Electrical power will be needed to power the filter, heater, and lights. The aquarium hood keeps the tank covered, which helps keep evaporation of the tank water to a minimum, and it also helps protect the fish from jumping out. Some species have a little too much energy for their own good.

Without a doubt a filtration system is essential. The filtration can be done by mechanical, chemical or biological methods, or a combination of these systems. Get as much information about each system before purchasing any system. Be sure you know what will be involved in cleaning or replacing the filter media.

Other pieces of equipment that you will need are a heater, a thermometer, and perhaps books for general information. Some additional items you might want to consider are chemicals such as aquarium salt—to help cure and prevent diseases; water conditioner—to remove chlorine from tap water; a bio-boost—to start the nitrogen cycle; and vitamins and minerals—to add to the general health of the fish.

Optional but recommended items

In for a penny, in for a pound. Now that you have gotten this far, here is another list of items to consider having:

  • Live Plants
  • Background
  • Rocks
  • Driftwood
  • Fish Net
  • Algae Scrubber
  • Ammonia Test Kit
  • Nitrite Test Kit
  • Nitrate Test Kit
  • pH Test Kit

The plants and decorations add interest and help keep fish healthy, and the testing kits are explained below.

How to set up the aquarium

Even new aquaria and equipment should be well rinsed with warm clean water before it is use. If an aquarium background (See article on aquarium backgrounds) is going to be used, it is easier to be placed on the tank before any water or decorations are added in the tank.

The tank should be placed on a level solid base away from direct sunlight. A sturdy aquarium stand is recommended to hold the weight and help prevent the possibility of a pressure crack.  With the tank resting in place, add rinsed aquarium gravel. (If an under gravel filter is used, place it first.)

Start filling the tank with lukewarm water by slowly pouring the water into the tank in such a way that it slides down a side before hitting the bottom of the tank. The purpose of this is to avoid displacing the gravel, and later the aquarium ornaments and filter. When the tank is ½ to 2/3 full, decorations, plants, and possibly the filtration system can be added. The decorations, plants, driftwood, and that sort of thing, adds interest to the look of the tank, but it also provides cover for the fish to hide in. Being able to hide helps the fish be less stressed, and they will live longer.

Continuing to add water with care will eliminate the need of reaching into the tank and repositioning the placements. When the tank is within 2” of the top add aquarium salt and water conditioner. Be sure to consult the package for directions.

Finish hooking up the filtration system. Place the heater and thermometer into the aquarium. (Follow the direction given with the heater.) Continue filling the aquarium with water to 1” of the top. Turn on the filter and heater, let everything cycle for at least 24 hours. Some adjustment to the heater may be necessary to keep the water at the desired temperature for the fish you intent to add. (Tropical fish 76-78 degrees and gold fish 70-72 degrees.)

After the tank has had the proper time to cycle, it is recommended that you test the water for the desired pH level for the fish you want to keep, and make any adjustments as needed. (Some additional information about pH can be found here). It is now, finally, time to add some fish to your tank.

It is recommended, especially for the beginner, to select fish species for their ability to withstand the nitrogen cycle. Some of the recommended fishes are Barbs, Swordtails, Danios, and some Tetras. A knowledgeable pet shop clerk can assist you in making the right selection. The first fish added to the aquarium will help establish a good nitrogen cycle.

Nitrogen Cycle

Nitrogen is the most common element in the atmosphere, and it is essential to all living things. However, most living things cannot get nitrogen out of the air on their own. The organisms that can, mostly bacteria, are called nitrogen-fixing. The cycle starts in your fish tank with the ammonia stage, when the fish give off urine and solid waste into the water. The ammonia would quickly build up in the water to levels that are toxic to fish. Fortunately, we have some helpers in the bacterial world.

Certain bacteria are able to convert the rising ammonia is nitrite, also toxic. But this product is converted with the help of another bacterium into nitrate. Nitrate is in a form that can be used by aquarium plants as a nitrogen food source. So, what the aquarium-keeper must do is to establish this process in the new tank.

Fortunately, the bacteria you need to grow in your tank are everywhere (in the air, water, etc.), but they need time to grow to suitable population levels in your tank to keep the ammonia levels down. This is why it is best to start with a few hardy fish that can tolerate initial rising ammonia levels till the bacteria really kick in. Testing kits can help you determine when this cycle is set up and in balance. Also, you will likely need to change out some of the tank water from time to time as another method of reducing ammonia levels.

This full process should take about 2 or more months, so do not get the most expensive fish right away. You may have some early casualties. With the nitrogen cycle established and the starter fish thriving it is time to add more fish to the tank. The size of the tank will determine the final number of fish. With the final number in mind a mixture if live bearers, schooling fish, catfish and algae eaters can be introduced into the community.

Adding varieties of fish serves more than just adding more fish to the tank. Variety adds to the interest of a tank and each variety can contribute to the health of the tank. As an example the catfish, one for every 5 gallons of water, are bottom feeders and will help consume the food that has fallen to the bottom of the tank. This in turn helps prevent the food from rotting and fouling the waters. The algae eaters, usually one for every 10 gallons, do just as the name implies. They eat algae and helps keep the algae controlled.

A well established aquarium will naturally do a lot to keep itself healthy. It will produce the bacteria that will help keep the nitrogen cycle active. Plants take up the nitrogen and carbon dioxide and give off oxygen. The fish will do their job of eating the bottom foods and eating algae. An aquarist must do his job of providing the final assist, periodic cleaning, and maintenance. But this rewarding hobby will provide you and your family with hours of enjoyment.

More about egg-laying fish

By Rita:

In an earlier post I briefly described the most common egg-laying style of fish in a fish tank aquarium, egg scattering, and provided some insight as to why these eggs often did not reach adulthood.  In this post I will discuss some of the other egg laying strategies. Each group is presented in order of parental attentiveness to the offspring.

The egg scatterers have no parental interest in the eggs or the fry.  They are also likely to eat their own eggs after the spawn.

The egg hangers on the other hand are not as apt to eat their own eggs.   The spawning fish lay and fertilize each egg then hang them by a fine, sticky thread from plants usually near the top of the aquarium.  Beyond that there is no parental care.   This group of fish includes Lyretail, Panchax, Lampeye, and Rivulus plus others.  Most of this group is not common to the average tropical fish aquaria.  One of the reasons is they are among the more expensive fish. The expense is due to the fact that it takes more time and space for breeding. The female will lay up to 200 eggs over a 20-day period.  The young will then hatch in a staggered period according to the day laid.  This can result in a hodgepodge of growing fry.  The younger fry is in danger of being eaten by the earlier hatched larger fry.

Nest builders are the another group and they take a slightly more active parental role. The nest is first prepared either by sticking bubbles together or gluing aquarium debris into a nest.  The eggs will be deposited into the nest.  The nest is then protected until the eggs hatch.  Once the fry hatch they are on their own. The fish that comprise this group are the Sticklebacks, Siamese Fighting-Fish and Gourami.

The most protective of their eggs and off spring is the egg hiders and the egg anchorers.  This group consists mostly of Cichlids and Dwarf Cichlids.  It also includes Angelfish, Jack Dempsey and a few others.  As the group name implies the eggs are attached to a surface either secluded (the egg hiders) or in the open.  Both partners concern themselves with preparation of the spawning bed, the care and protection of the eggs, and the care of the fry for a period of time after hatching.

To leave a pair of spawning fish in a community tank is always a risk. A properly prepared breeding tank would greatly increase the chances of having viable young.

Diverse food for aquarium fish

In a previous post I touched lightly on the importance of giving aquarium fish live food. Live food provides a more natural and a more balanced diet than a commercially prepared fish food. The prepared foods should only be considered as a basic diet, not the total diet.

A typical way of feeding aquarium fish is to sprinkle a quantity of dry food into the aquarium. As the food slowly drifts to the bottom the fish try to get a share. If the fish are unable to eat all of the food, it settles into the aquarium gravel. Bottom feeders and smaller fishes will eat some of the settled food but if it is allowed to stay in the tank it will rot and foul even a large fish tank. Live food not only gives the fish more of the nutriments they need, it permits the fish to feed in a more natural manor.

Below I have listed some of the more common live foods that can be used in an aquarium. My list is by no means complete. It is intended as an introduction only. You can purchase these foods, or even collect them yourself if you wish.

BLOODWORMS & GLASS WORMS – are not worms but the larval form of a fly. Both larvae make an excellent food for mature fish but should not be in a tank with small fry; the larvae are capable of catching and killing the fry.

TUBIFEX WORMS – is probably the most used worm in an aquarium as most dealers stock tubifex worms year around. They can however be found in bodies of water that is rich in organic and vegetable wastes.

MICROWORMS – is a small worm that was discovered to be easily cultivated and made an excellent food for small fish. Other worms that make good fish food include the Grindal worm, White worm and the common earthworm. It is better to not make a steady diet of any one thing. Larger worms should be fed in smaller easier to swallow pieces. To avoid a mushy mess while cutting up the worms use a quick-freeze method. Quickly freeze the worms. When you want to do a feeding, take out the amount of worms needed and cut them with a razor to the desired size.

OTHER – The common housefly is also an excellent food for the fish tank Aquarium. Be aware that only the swatted flies are acceptable as fish food. Flies that have been killed with insecticides are poisonous to the fish that eats them.
