We all know how difficult it is to identify the sex of these fish, so please post a picture in here and we'll try to help you (or at least give an educated guess!).
Luckly get a chance to buy this wild cought from a person who give it up.
He had it for few years and had no chance to breed it.
Please help to ID it and I am happy to have a new zebra into my group no matter it is a male or female.

This is one of those fish when you first look at it you say male but when you look closer you see female traits such as you have listed. I have a fish that looks like a male as well but not as hairy or as large as the other two males i have. This fish never goes into caves just hangs about under rock ledges, no golden eggs yet, so i can't confirm male or female maybe a bit of both and i will never know.
The vent on your fish does look female to me but i am no expert .
