How many fish should I put in my tank?

The general rule of thumb is 1 inch of fish per gallon of water. That will vary depending on the type of fish, tank decorations, live plants, and the chosen method of filtration.

How deep should my pond be for my fish to survive the winter?

Ideally, outdoor ponds thrive best at a depth of 36 inches. However, that may be difficult to reach. Never attempt an outdoor pond at less than 18 inches of depth.

How often should I feed my fish?

Most fish do not have to be fed every day. It is best to feed every other day. In doing so you reduce the amount of decaying food and waste in your tank, which will improve overall water quality.

Why does the water in my tank get cloudy a few days after I set it up?

Your tank is "cycling." Cycling is a term used to describe the process that transforms new aquariums into established biological filters. At the start of a new tank, fish waste and uneaten food decay form bacteria and ammonia in the bed of your tank. The bacteria transforms the ammonia into nitrites and eventually into nitrates. When the ammonia and nitrite level reaches zero, the cycle is complete. The water should be clear, and additional fish can be added. This should take between 3 and 7 days.

Why does my tank get green?

Algae is the cause. It is an essential part of an aquarium's natural biological filter. No healthy aquarium should be without some green algae, but too much can cause respiratory problems and eventually become toxic to your fish. To limit the growth of algae, move your tank away from direct light sources, away from windows or doors, and keep the aquarium light off for at least 8 hours a day.
