plate corals
 

do these things grow and grow and grow until they take up the whole tank? I got one about 4 months ago and since then it's grown to about 6" in diameter. I recently moved it because grew into the side of the tank and was starting to crawl up and now it's growing to fill the spot it's in...I'm getting scared that it's going to start eating fish.

Sounds like it might be time to frag it. It will continue to grow as long as it has contact will a surface to grow on.

I guess LPS are difficult to frag without killing it...I think I'll just let it grow.
