Okay so i had two mollies that i got from one store when suddenly one of them died. i got two more mollies to keep the other one company but from a different store. the two i just got seem to stick together a lot and i cant tell if my one that i have had is unhappy. She doesnt have clamped fins or signs that she is being picked on but she is always by herself when the other two are together. Is it possible that she is unhappy or maybe just a loner? this may be a stupid question but any help is greatly appreciated also the ones i have are two females and one male if that helps. its one female and the male that are always together.
