Rhode Island's great for snorkeling (at least i think so.) you should definetly check out the beaches on Ft Wetherill. They have great spots for native fish and if you snorkel around in the coves during the summer, you can catch juvenile Spotfin Butterfly Fish (no biiger than the size of a quarter), Boston Bean Cowfish, and thats the only damsel ive ever seen there. One really interesting fish ive seen a lot more of is the Northern Puffer. Have on in my reef tank and it's doing great!
good news about the cunner: He's been coming out of the hole he was forced into by the damsel alot today and has been doing great! i just put some frozen brine shrimp and he was eating his fill. Still looks a little emasiated and has some missing scaled/nipped fins, but i think he's going to be fine.
