No need to control them. They seem to come and go with different stages of the tank. These are harmless.

If you feel there becoming invasive then you could always try aiptasia x. But if Mr X says they won't take over, I'd tend to believe him.

Yeah Mr.X is very helpful and I want thank him for the help he has gave me for the past year probably

I have yet to see these take over a tank. Just like BigRed says, you can kill them manually just like aptasia or majano anemones if need be, but in my experience, their numbers rise and fall for seemingly no apparent reason.

Ok that seems fair hahaa
