Other than the female being bigger than the male, how can one distinguish between the sexes?

Fishbase doesnt give much info. [/url]

It is easy to ID the fish when they are mature and in breeding condition.
Males will have a brilliant green underside with brilliant green Pectrol and ventral fins, Females will lack this.

Some say you can distinguish males and female by the presence of or lack of the caudal ocellus.
This is not nessesarily the case (especially in young fish) as I have seen females with a distinct and developed Caudal ocellus.

Down here we have gotten some females with bright green fins and an ocellus, but the ocellus usually lacks the halo around it seen in the males. So far we are 100% on sexing externally on a couple hundred fish.

I just went through about 30 fish (5-7 inches), trying to find any sexual difference. Nothing jumps out at me. All have ocellus. a few may seem to have more of a halo, but I might be imagining it.
Dredcon, If I sent you pics, do you think you could sex them at this size? Want to try?

This one is honed up any you can see the halo really well. After spawning season the halo is still there, but not as bright. I do not know how well this works for small ones.

Not well, none of mine have a halo that well defined. I will send you some pics, and maybe you can see something that I may be missing.
