OK this is my dillemma I need to increase the school of fish I already have in my 36 gallon bow. In the past I have tried having 2 bolivian rams in the tank but when I have a few in the tank one only seems to survive. In the past I tried having 4 bolivian rams and then tried 2. I am down to one male and he has been in the tank for a long time and is flourishing. I think the deaths may have been from stress I know they can be territorial having 4 in the tank at one time may have been too many. If I were to chance it again I would want to get a female but how do you tell them apart. I know what the male looks like but they say that sometimes that females can have that structure as well. Should I just leave the one and just increase the other schools of fish. Not sure what to do.
