if you want sharks, look into cat sharks, like the banded coral cat and the spotted cats. they are smaller versions of a potential HUGE problem, and they look cool. stingrays are all like witty says, they need plenty of room and are definitely a burying creature. they get sick easily, so i wouldnt recommend any fish that may introduce a threat upon them. im not sure about flounder, though..... sounds cool, i think. good luck and welcome to RS!
