I have a similar question. Several months ago, I was given a mixed group of Endler's fry: tigers and wild-type. As they mature I can easily tell male tigers from male wild-type, and can separate them. But the females all look the same, at least to me. I am mainly interested in breeding the tigers. If I fail to separate the wild-type females from the tiger males, will I get tigers, or wild-type, or some intermediate color variety?
