For a 375, stick with cat sharks. The coral, marbled, or the Bali are you best bets. The brown banded gets rather large. A gray bamboo or Arabian are smaller options. As for fish it is hit or miss. I've never had luck period. So I avoid all fish. I know others that have with your selections. Groupers are ridiculous aggressive feeders though and may out compete the Sharks. As for the ray, the Cortez is a good small ray but they like the temps a little lower. Avoid torpedoes and blue spotted ribbon tail rays, they have a bad track record.
