Hydroids??? Help!

[Fiesty]

So i think i have some hydroids and need help. Small brown colonial type i believe? Not terrible but quite a few spots around the tank. I have used some kalk paste on them but am lazy and would love to find a natural predator / way to eradicate or control. The tank is a 200 gallon with lots of live rock so no eazy way to reasonably get into all the areas to treat by hand.

Everything else in tank going well exect these little sukkas! I did add a pyramid butterfly recently and think i still have some pepermint shrimp as well. Thanks for your help and suggestions!

Sometimes Filefish will eat them. But they might eat a bit of your corals, too.

I had one but when went down to 1 tank had too many fish so sold him. Maybe he use to eat them and why they popping up now? Only ever saw him nip at 1 LPS one time. Might have to try another
