Hi everyone, my little Peachy is suffering with dropsy and I have decided to very humanely euthanize him to stop his suffering. He is in a filtered, heated 1.5 gallon tank and has been its only inhabitant.
What should I do with the tank now? Can I introduce a new fish into the tank or will the dropsy be contagious? I don't want to lose the cycle and totally break the tank down to clean if I don't have to.
What do you guys do after a disease?
