i've started out with 4 juvie cresteds. they are all right now together in a 55 gallon tank. untill i can determine sex i'm planning on keeping them together. however, one seems he could be developing the bulge so i'm assuming possibly male. the other three do not show any signs yet of being male. the interesting thing is that the one showing the buldge will hang by himself where as the other three curl up together on the same leaf. Am I just being to hopefull? or can this be a sign of sex?
