Hitch Hiker ID

[Kraff813]

Can anyone ID these? They’re randomly scattered around my rock. They don’t have an obvious shell like vermetid snails. They literally just come out from the rock.I’ve also had vermetid snails in a prior tank and these are different. I’m expecting a similar filter feeder with a stringy/fuzzy “tentacle”. They’re irritating corals.

There are so many, it’s impossible to manually address. I could get a six line/melanious wrasse, but I have a colony(?) 8 Pom Pom crabs I feel like might become snacks.

Any other rock picking wrasse that won’t eat tiny crabs?

Thanks in advance.

Lookup digitate hydroids on here and you should find some info.
