Help with ID please

[scope2reef]

Got a used tank with corals. I'd appreciate your help with ID of these two:
One I guess is frogspawn?
Other two are same with and without "tentacles" retracted.

Picture one is a Hammer Coral.

Looks like Gsp and a hammer

Gsp, or GSP is Green Star Polyps

Thank you. Will now research on how to care for them.

Forgot about this one in my tank. What coral is this?

Cabbage leather? (Sinularia brassica)

Biggest regret with my tank....adding Green Star Polyp. That stuff will grow over everything and its a nightmare to get rid of. Put it on an island far away from anything else if you decided to keep it.

You can grow the GSP on the back wall of the tank. It is really easy to get them off the glass and cut to about 1 square inch and sell/trade it to LFS. It really looks nice to have a back wall bright striking green in color.
