I think this is a parasite eater they usually latch on sharks and bigger fish right?

It used to be at LFS up by me but was sold to someone in the city. Definitely cool since its head is big suction cup. But you are correct it attaches to bigger fish and lets them do the swimming while it eats small fish swimming around it.

Pretty cool fish ? They had or have one at underwater world, for $60 but it was a mean sucker. It would try to bite you if you stuck your hand in the tank.
