Here is my original post about my new at-least-partially-albino fish (and my avatar, Kaspar).
I... think he may be a she.
S/he gorged him/herself on frozen brine shrimp tonight, and I thought I saw an egg spot. S/he also doesn't have a visible beard, but s/he is a very young fish. About as big across as a US nickel, not counting caudal fin.
I mean... I know how to sex bettas. But this one has me baffled. I've never had one this young before. How can I tell? Might his/her light color make it more difficult?
This fish is also blind. I've heard that one can put a sighted male in with a blind male, as the blind male is no threat because he doesn't have a visual territory. I have two other males, but that still wouldn't prove anything, I don't think, because a male will fight a female if either one isn't ready for breeding.
