Tank maintenance is one of the most important parts to having healthy fish. The tank needs to be vacuumed at least once every two weeks. Try to do a 10-20% water change every week. Once a year you should completely start over. Drain all water, clean the tank, and rinse the gravel.

Aeration in your tank is crucial for having healthy fish. The filter will not provide enough oxygen. You should have at least one device for a 10-20 gallon tank and two for a tank that is larger than 30 gallons.

Fish need to rest too! Turn the lights out at night so they can get some sleep. They need about 12 hours of light and 12 hours of darkness.

When feeding fish you don't have to feed the same old food everyday. Fish crave different types of food. First you need to find out if your fish are insectivores, carnivores, herbivores, omnivores. Then you can feed them different things according to their preference.

Fish food is divided into four different food groups. The most common flake food, frozen food, live food, and household food. Be careful with the live food because they can carry diseases that can infect your fish.

What do I do when algae takes over? Some things to try to decrease your algae growth are algae eaters, buy some aquarium plants, decrease the light in your aquarium, scrap the glass of your aquarium, and do water changes more regularly.

When buying fish for your tank for the first time be sure to buy hardy fish. Sometimes is takes awhile for your tank to adjust and to get your water tested the way it needs to be.

There is three different types of filters for aquariums. They are a box filter, an under gravel filter, and an external power filter. The under gravel filter is a good option. It requires less maintenance and has more aeration for your fish.
