Are you serious??? Fish poop? No way. I mean, it's enormous, and pink! Corwin is a just a tiny betta and he's the only one in the tank. Usually his poop is small and the color of his pellets. Now, some of you may remember that I had some problems a while back when his poop looked large and white, kind of like rice. But this, this just can't be...pink and cauliflower-like? I mean, what could he possibly have been eating??
