Males get bigger then females also the anal and dorsal fins become pointed sooner then the females. When a bit bigger the males dorsal fin will keeping getting bigger creating a long pointed extension. They have to have a lil bit of size 2-3" before you could properly sex them.

Not easy when they're juvies. See my thread here ... http://www.monsterfishkeepers.com/forums/showthread.php?464652-Firemouth-Breeding Most seemed to think that mine was a female but he turned out to be a male, and an absolute beast of a male too.

Not as easy as you think in smaller specimens. Maturer females can get long extensions aswell and their colors are almost the same as males. Generally speaking Males tend to get larger, have longer bodies and snouts, larger mouths, a more dominant disposition, and their fin extensions are consistently longer (but never rule out the possibility the the fins have been damaged and are growing back)... So fins and coloration are not reliable but, size, shape and attitude are and in sexually active specimens there's venting, with the female having the larger blunter tube.
