Yes sure it looks male n nicely colouring up too.
What do you feed your stock
How big a tank is he in , who are the other occupants in it
Can definitely confirm this claim. Mine eventually accelerated their growth rate once they hit about 6", and don't appear to be slowing down. My adopted male is now regularly staring down a 12" Oscar and he's maybe 9".He will hit a growth spurt, once he hits 5 or so inches he will soar to 10 before you know it
