So i have a pair of Angels that finally laid eggs last week, I saw which on did, and the other went over as to fertilize them, after a couple days they were all infertile, i figured because its there first time, But i went on vacation for the last four days and came back to another batch of eggs, now its been exactly one week since the last one. and they is some going infertile. Is it possible i have a pair of two females? Thanks Everyone
