	SPS Small Polyped Scleractinians - Sometimes known as Small Polyped Stony corals. These are hard corals that have extremely small polyps. They are typically on the difficult side and require Metal Halide lighting or dense Power Compact or T5 arrays. These corals are prized for their rareness and ability to be easily fragged into multiple colonies.

	LPS Large Polyped Stony corals – In the aquarium hobby this is a common division of the species of stony corals based upon the visual assessment of the size of the polyps. Corals in this category were among the first stony corals to be kept successfully in captivity and include many very beautiful species. Commonly kept Genera include Euphyllia (hammer/frogspawn coral), Favia (brain coral), Plerogyra (bubble coral), Lobophyllia (meat/tooth coral), and Caulastrea (candycane coral). LPS corals also include the popular solitary non-colonial stony corals such as Fungia (plate coral), Cynarina (button coral), Trachyphyllia (open brain coral), and Herpolitha (tongue coral). Like their SPS counterparts, LPS corals require good water quality, intense lighting of the appropriate spectrum, adequate water movement and regular supplementation of calcium.

What size is the tank for one? Two: a clown tang is in the same family as the sohal and really shouldn't be in anything smaller than a 300g for their sake and the sake of the rest of your livestock. At around the 8"-9" mark (about maturity) they can snap and go completely ballistic. I've known them to knock over corals and attack fish even in a 400+gal. They get very large and are an aggressive tang. Three: the Achilles while an awesome looking fish also gets very large and more often than not gets aggressive at adult sizes. When I say they get aggressive I mean more so than most fish, let alone tangs.

What kind of fish are you looking for? Something in the same size range as the tang or something in a different direction?

FYI, Jonathan's tank is 400 gallons. But I agree that a clown tang is likely not the best choice. They get very aggressive.
