it is somewhat difficult to find good info on this fish so i came here. i want a pair of the but my lfs tells me that it is better to have three of them for two reasons. first is one of them will become a male and that will offset the agressive courting of one male to one female between two females and one male. reason two is that it is the same price to get three females and it is difficult to get a male in the store. what do you guys think. im pretty sure i dont have sufficient space for 3 of these beautiful fish. what do u guys think or recommend?
