"Chalice" is just a common name for many different corals like Echinophyllia, Echinopora, Oxypora,etc..... What you have is a type of Echinophyllia. It might be aspera. It is hard to tell. Looks like that guy has seen better days. Some actually like more light. What do you have on your tank? A lot of people will say to give it less light but if the corals is used to more light it will starve. Are you running halides? If so what wattage and what sized tank?
