I still need to post pics, of BOTH the fry that are in there!
A new one showed up today, less than half the size of the one I found previously. The first one was so big, that I assumed the mother must have been holding when I moved her into the bigger tank, but this one is so small, it was certainly born in this tank. I still have no idea who the parents are, as none of the fish spend any time in the area of the hole these guys keep appearing from! This one looks much more like I would expect fry to look, greyish brown, only faint markings... while the first one is a nice blue with dark bars. Anyway, I'll post pics when I remember to take them!
