I just picked up a blue spotted puffer from a guy from facebook yesterday. The fish was injured from his grouper, and he wanted it re-homed. The wounds are healed, and its looks like its getting its coloration back. He told me that this puffer was completely reef safe in his tank, and left everything alone including shrimp and CUC. I feed my fish Rods food and Nori, and last night the puffer ate some of the rods that I put in. So far it has completely left my CUC alone, and just seems pretty content to just swim around. What should I feed this fish to wear down its teeth? The guy I got the fish from says he puts in ghost shrimp and the puffer eats those, are they enough to wear down the fish? I just dont know about the ghost shrimp because 1. they are freshwater, and 2. they might give the puffer the wrong idea, and make it think that it can eat my CUC. Advice please.
