I have a couple of Salvinis and I am pretty sure that one is female and one is male. The one that I believe is a male is about 3 1/2-4 inches and the female is around 2 1/2-3 inches. The male has dug out a spot between two rocks and he's been chasing other fish away from it and acting aggressive toward the female. Are my Salvinis old enough to breed or are they bluffing? Thanks in advance--I tried to find the answer on my own and didn't come up with much information.
