I've just noticed that one of my guppy fry has something hanging out of it's stomach I scooped it up and put it in a makeshift qt tank until I figure out what happened. I also ousted my molly (who is becoming quite aggressive) into a different tank on his own in case he took a chomp out of him, the only other fish in there are some molly fry and a couple of other guppy fry. It looks flesh coloured with pink tones to it and, for his size, is quite big. Tried to take pics but without much success. Is it likely that the molly took a bite or is it more likely a parasite?
