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!).
They look male to me too . I sure hope your females are just better at hiding!
The pictures can't be posted from the gallery because the url for them doesn't end in .jpg so the bb software doesn't recognize it as an img. There is a workaround for it that Tim applied at holics that uses what they call a siteimg tag instead, I think.
