just got this guy with a squirril fish (daughter had to have a pink fish) anyway i wanted to try my hand at some corals but im reading they may not be to kind to that. the tank he was in when i bought him had a mass of stuff in it though. im also adding some snails and hermit crabs for cleanup crew since they are cheap and expendable. what can i do to spruce up the tank a bit and also where can i get saltwater ghost shrimp?
