I have a 55 gallon tank with four fantail goldfish and a few little ottocinclus for algae control. Last night the smallest of the goldfish, about 2" in length, tried to swallow one of the ottos. This morning he still has the tail sticking out of his mouth. I'm afraid its stuck in his throat. I caught him in a net and tried to gently pull it out, but it's stuck pretty good. I don't see how he can survive like this.
Is there anything I can do?
