What eats these “worms”??? Help needed!!

[fity2pounder]

Looking for name/ID on these worms (this is about the best picture I can get unfortunately). They have a very soft “shell” and tend to live in holes and crevices. They sting soft corals and eventually the corals will die from not opening. These things have propagated and are now all over my tanks so dipping is not an option. What will eat these? Help would be MUCH appreciated!!

I have tried (unsuccessfully):
1. Six line wrasses
2. Yellow corris wrasses (jumped, no option for a cover on my tanks)
3. Arrow crabs (set a worm right in front of one of these and it wasn’t the slight bit interested)
4. Mexican and blue leg hermits
5. Peppermint shrimp

They are not worms but Digitate Hydroids
They don’t really sting but can irritate corals.
they died back in my tank but the yellow wrasse said to take some of it.
