Per profile: I am a novice SW 29g tank with 27lbs LR, hermits and snails, apparently bristle worms, and 2 false percs, a royal gramma, and a fire fish: very community and peaceful. I plan to add a LM blenny and a skunk cleaner shrimp soon, and go light reef by summer (anemone and soft corals). Looking for suggestions on adding a couple more fish, including a peaceful "centerpiece" fish. Recommendations and cautions are welcome. Thanks for input in advance.
