What's this bad boy's gender? It's extremely to get a picture of it underwater. It lives in a really large pond, it's a miracle I managed to get these pictures in the first place, it's around 3-4 inches ATM.
It's hard to tell in that pic but when it's in in tank look for spotting on the unpaired fins, mainly the caudal (tail) and the dorsal. Males show this at a very small size.
