there are two different types of palythoas there, and Green star polyp. I'm assuming your not asking about the GSP. I dont know the names off hand but they have real easy care and are extremely hardy (I havent killed any yet I accidently left some out while fragging for more than an hour), med to high light, moderate to low flow, and will accept meaty foods of any type including flake, pellet, shrimp, squid, clam, fish, cyclops, larger planktonic foods as well. they will develop faster with regular feedings. remember if you spot feed these on a regular basis consider it adding to your bioload like you would a fish for they eat and defecate.
