How does one get rid of Digitate Hydroids? They are spreading on all my rock.

Blowtorch or bleach the rock..  I did not find anything that would eat them

Sea Hare will eat colonial hydroids...not sure about digitate?

Cant remove the rock it is epoxied together.

I had the colonial ones. Nuked the rock. Still have the digit ate in this tank but their numbers have basically dropped to zero as the tank matured.

I have been doing some research and saw several post saying the same thing

I had these in one of my seahorse setups once but they basically died off.  I was always fascinated with how they could move around and how they elongated to strike at food.  Since they weren't considered a threat to my seahorses, I let them be.
