Ok so I bought a 65g yesterday(setting it up tonight or tomorrow) and I have 3 female bettas who all live seperatly...The question is with that amount of space do you thin it may be possible to put them together??even if I just put 2 toghether cause one has her own tank...its just that I'm selling my 30g and want to use my 10g as a hospital tank and don't want to be constantly medicating one of them in the hospital if she's not sick...If not I will go get her a tank of her own and put just one in the 65g....
