I've been doing some research on a new fish to introduce into the 55 gal
. I was wondering if anyone can tell me any experiences about iridescent sharks. They're kind of goofy looking and cute. Also, the size. I saw one site online that said they get about 6" and another that says 12". Then I saw a thread on this site while searching that they can get 3-4'! Lol, those are big differences in size! Should I stay away from that fish?
