Pretty hardy coral... you shouldn't have a problem as long as you keep your water clean. Scolys prefer low to medium light, and low flow. It needs *some* flow to keep it cleaned off, but you don't really want to see it flapping around. Normal reef conditions otherwise... calcium 380-420, alkalinity 8-12
dkH, specific gravity 1.025ish, and you should do fine with it.
What type of lighting do you have?
Wow... $30. I've seen some mislabeled corals in some smaller shops around me that would be good deals for someone, but never something like that!
