Another thing, the male orange Sailfin is occasionally swishing himself against a stone in the bottom. Now I have seen females do this when in labor, but this is the MALE and he is doing it, too. Hard to say if any others are acting oddly... The female talked about came out for a while, swims OK, but stays near the bottom, not angling for food much. She might be young, have had her for 3 months. As far as pregnant, she has slight belly, but not much.
