I have a tank with zebra & leopard danios, neon tetras, a Siamese algae eater, Cory catfish and a baby albino bristlenose pleco. Today I saw that one of the fish had eaten the pleco but I don't know which fish would have done it. If you know which one may have eaten it, please tell me!
It could have died over night and the other fish decided to eat him. I've had it happen a few times when I had fish either die over night or when I'm away at work. Fish will eat dead fish.
