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!).
I edited my original post and added 2 more photos. I don't like disturbing the zebras, so I took the opportunity to take a photo of them when I give the bigger zebra a bigger cave.
Yes, Zebra #1 stays in the cave. I remembered reading an article on here somewhere that the female tries to seduce the male into here cave by curling inside it. Well, that's what it does all the time. The original cave was actually just a trial I made before and was small. Since it is has grown allot, practically adult size, I figured it was time to move it into a bigger cave.
The zebra in pic #2 also stays in the cave, but not in there all the time, as it always peeks it's head out. This is a pic of it's typical "checking me out" position...
Cool. My 1st zeb bought was fortunate to be a female, the 2nd zeb a male. Too bad there's probably no chance of them breeding. My only hopes are the new juveniles a bought a few weeks ago will fill in as the dominant male.
