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 finally found some zebra plecos to buy here in Hawaii and am wodering what sex they are. Can anyone please help me? They are both a little over two inches.
I would have to disagree, I still think that top one is male. The pectorals have that tell tale straight spot in them that seems to be a reliable indicator for males. The picture for the second one makes it difficult to tell at all.
Keep in mind, in my group of 11, I was told I had everything from all females, to almost no females. I'd decided they were gay and I was just going to ignore them and not worry about the problem for awhile. They spawned within a few weeks . Telling sex from pictures without a wide assortment of angles for each fish is just guessing, IMO.
Give them tightly fit caves. If they both use them, they're male .
Could well be right Barbie, I am looking at the primary crescent shape of the Pectorial fins and the top profile of the head. However, as stated they are sightly longer than I would expect, so I might be completely off the mark Maybe in a few months time, after some fattening up it will be easier to tell.

Welcome to the forum.
I would say that the top picture is a Male. especially from seeing the long cheek odontodes/bristles.
The bottom picture is a little out of focus so therefore cannot be sure. If it has cheek bristles as long as the one in the top picture, it is a male. If it has much smaller bristles , not much longer than the cheek groove,than it is a female .
