my male clown fish just decided he hates feather dusters. I have 3 in my tank, and they were almost always open unless i scared it, or a snail or something got too close, but the last few days, my male clown tends to their eggs, and then about every two minutes, he leaves the clutch just to go harass the dusters and nip them even after they closed up and returns to the eggs.
i don't know what made him so racist towards dusters! its almost funny how much time the damn thing spends just trying to keep them from coming out
