Hello tzhanks,
I am a new member and have an Oceanic Biocube 14 that is well established with pods, cleaner shrimp, hermit crabs, 2 clowns and plenty of food for a mandarin. This will be my last fish since my focus at this point will be on the corals. I built the reef with very porous live rock so there are plenty of places for the mandarin to find pods as well as cover. Thanks.
