This carnivore is quite a character, coming over to "visit" with you whenever you approach the tank. With his iridescent blue/green eyes, strange nostrils, tiny little pectoral fins, and spines, he can be fascinating to watch.
He is a carnivore, and can give you a nip if he thinks your finger is food.
I just loved his eyes! I discovered, however, that I'm better at keeping non-carnivores, so he went back to the shop.
