Need Help- Aptasia, Hydroids or Red Star Polyps?

Wasn't sure where to post this? I have a 100g FOWLR tank that has been running for close to 14 years now! I recently noticed 3 or 4 colonies of polyps on a few rocks at the top of the tank. In the past I had Aptasia, added a Scat and he took care of that. I have NOT added anything recently other than a few Hermit Crabs and Turbo snails and Black Fin "shark".

My local LFS thinks its red star polyps and not dangerous but will spread. From doing some research I think they might be Hydroids, which seem alot worse. The LFS recommends a Chocolate Chip Star as they think it will eat the polyps. Not sure what to do next?

They are very tiny and will retract into their tube if touched.

Most butterflies will take care of a problem like this.

Thanks, I might have to add a Butterfly to the tank. The LFS recommended a Chocolate Chip Starfish for some reason, while he is cool he hasn't touched the polyps.

Perhaps lights out for several weeks?

I've cut down on my feedings, got a new skimmer and have cut my lights back to about 5 hours per day. I was thinking of going dark for a few days, but am concerned how this will affect my fish?

As I understand, and I could be wrong. Fish don't require lights. If it is a fish only tank, why are the polyps a problem?
Cheers! Mark

Look like colonial hydroids. Lights out won't do anything if so. I've had Peppermint shrimp eat them but they're hit or miss whether they will.

Will a Butterfly eat them? Or best to try a Peppermint shrimp? Or, best to just take the couple of rock out that have them and trash the rock? It is a fish-only tank, but dont want these things taking over!

I’d go butterfly route. Something halfway easy and cheap, maybe a raccoon.

Thanks for the advice everyone. I'll stop by the LFS today and see what my options are.
