My LFS has both Blue Coral Banded Shrimp and Pom Pom crabs in stock. My tank is fully stocked with fish, so I've been looking into fleshing out the tank with a few more inverts. Current invert stocking is a Peppermint shrimp, Conch, and some trochus snails. Advice on one or the other with current stocking, or both. I'd like both. Fish are a pair of clowns and a large-ish royal gramma. Coral is a bunch of sps and lps. Thanks in advance.
