My favorite fish in my tank are two clowns, one Yellow tang ( needs a couple friends, lonely guy), One Atlantic sea Urchin( craziest and most fascinating) and a few more and a good clean up crew. My favorite coral is my tank is a Green Fluorescent Mushroom then the usual Anemones, Zooanthids and Capnella. All this is structured around Fiji live rock . It takes some time to learn and mistakes are and were very expensive.
