I'm looking to add to my CUC in the frogfish tank. Currently have a couple Astria snails and a margarita along with a couple small hermits and a large Fire Shrimp (He'll be getting moved to the 60 once the frog grows a bit more, currently 3x his size). Looking to add more but want to be sure whatever goes in will be safe from him and safe for him. Don't want him getting pinched or attacked by anything.
