To see the fish gently touch the tank. Inside you will find many different fish. Some are loners like the male Beta (Sampson), the Catfish (Banjo) and the Pleco (Chewy). Others like to swim in schools like the Danios. The Angel Fish (Huey & Dewy) usually do best in pairs. The big guy (Rudy) is a Ryukin Goldfish. I only hae one of them because they are so large. There are also some baby fish swimming around. I can't keep track of them....they keep poping up all over.
Fish need clean water, an air pump, and food. They are very relaxing to watch. They are also the quietest of my pets.
