Maze coral that does better under low to moderate light

Looks to be a platygyra, also known as a maze brain coral.

Can it be placed next to an acan?

Will most likely sting anything near it, mine do. They send out sweepers at night. An a an may be able to fight back, I’d try it but be prepared to move it.

They require basically the same light intensity. As with any coral, you need to be aware of potential sweeper tentacles that can sting neighboring corals. Some corals carry a stronger sting than others. Galaxea coral has a strong sting and 3-4 inch sweeper tentacles to give you an example.
