We need to clean a small fish tank that holds a male and female betta We don't know how to tell if there might be eggs in the tank Is it all right to change the water?

Answer 1

If you are following the basic rules for keeping fish which are . :- 1 inch of fish needs a minimum of 1 gallon of water. Every tank needs a permanently running cycled filter. :- Every tank needs at least 50% of its water replaced every week. There should rarely be a need to empty the tank completely. Bettas are bubble nest builders so if there are eggs they will be in a mass of bubbles at the surface of the tank. A male Betta will not tolerate another Betta in its tank with him so if you have two Bettas in a tank they are either too young to fight or they are two females that will not normally fight. To clean the tank you should put the fish into a large container containing water of the same temperature as that of the Bettas tank. You clean the tank properly and set it up (don't forget to add some chlorine remover) and please do not replace or remove all the filter medium. Some of the bacteria are needed to keep the filter working properly. Then equalise the water temperature before returning the fish.
