Thanks guys. 20 and over: I must not know what to look for - I have not found many options online. I have Caulastrea, GSP, leathers, zoas, mushrooms, polyps, Blue ridge, and duncans. For fish, tomato clown, damsel, dottyback, blenny, fairy wrasse, sandsifting & citron gobys, sea stars, urchin and CUC of various hermits crabs and snails. For corals, hoping one day to be able to have more LPS and maybe one day some SPS. For fish, hoping to get a copper band to help with any aiptaisa. Oracle Reefer: What fixture manufacturer and model are you using please?
