Provide your fish with a diet of commercially prepared fish food. Store it in a cool, dry place for no more than a few months. Remove waste and uneaten food with a net every other day. Rinse the net thoroughly before and after use to avoid the potential spread of infection. Keep a canopy or hood over the tank at all times.
Some fish are jumpers.
Don t let your fish get stressed by poor water conditions, drastic lighting changes or constant activity outside the tank. These things will lower their resistance to disease. The slower fish will not get enough to eat, and the others will be overfed. Discuss what types of fish are compatible in a tank and which to keep separate some species can be very territorial and will kill other fish. Inc. How things get done.
