Sexing Peacock Bass

[ajbassmaster]

Ok I have read that you can vent them to find out the sex but I know males develop the hump. I have one about 14 inches and it is in a tank with a 14 inch pacu and a 7-8 inch flowerhorn. I have also heard that they will only develop a hump if they are with other pbass. Is this true? or will it (if its a male) develop a hump even with other types of fish around? I would think it would develop even with other species but I would like a second opinion.
Thanks

P.S. The fish im talking about is the one in my avatar!

I would say its not necessarily true but my 8 inch mono had a hump but it was with other pbass. But imo i would say no. I could be totally wrong though.

Here are some older pics, it was about 11-12 inches. I will get some new pics eventually, need batteries for my camera.

It looks too small to have a hump yet- that's assuming it's a male.

Alot of times a dead give away that a Cichla is a female is the abdominal area,as a female is 2/3 Uterus.

Interested in the sex of my humpless bass. They are about 17-19cm / 7 or so inches, fairly small still.
