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!).
ok bought a pair of zebras and i just want to check iv definatley got a female. i took this picture of the female this morning and i want to verify she is infact a female.
she hangs around in nooks and crannys as my 2 males both have a cave each.
FINGERS CROSSED!
My Pleco's:
4 x L46
5 x L174
5 x L134
5 x L287
5 x L257
2 x L236
The problem is that the picture isn't clear enough for you to see the distinguishing features. The fins have been chewed enough you can't use them for reference and the angle of the shot makes it look more cheeky (male). If you can try for another shot or two from directly over the fish looking down and take 20 or 30 shots til you get a couple that are nice and crisp, then we can probably be more help. Sorry! Noone likes to be the bearer of bad news, so the post just doesn't get answered. With the only picture for reference, I'd say male, but honestly, without a clearer shot that's literally a guess from the vague shape I can see....
