Yes I think it is a Chilean catshark.The catsharks won't eat the damsels? The fish place didn't recommend any of those sharks. It is just what he had. He told me the nurse and wobbegong will get way to large for my tank and need a large pond. I just wasn't sure if I can trust him. You know how fish store employees are. He said my best best was a coral catshark. He ordered 2 of them for me and I picked them up on Friday. He even threw in a free zebra bamboo shark. He said that it stays very small.
