Lol, I'm so not good with sexing them but I ordered mine from private breeders so I figured they must know, right? I always look for the egg spot, but IMO Belle has the body shape of a female. I have seen quite a few girls with longer fins like hers :)
I have had my current three girls since the 11th in one gallon temporary tanks. I'm obviously not going to put just three in the tank, but I am planning on QTing the new girls for at least two weeks. I'd love to have them all in the big tank right now but I'm way too paranoid to take chances. I love my girls too much to put them in danger by being impatient D: I'm sure they'd love the extra swimming space but they are getting daily water changes and two of them are still very tiny. My biggest girl (Okami) is recovering from fin rot because she had some damage on her caudal fin from shipping. She is healing very quickly, though, and all three are super active and spunky :) Okami is a jumper, too!!! All three are voracious eaters but the smaller two haven't jumped yet. I get a little nervous to open Okami's lid, lolololol.
