Hi guys,
I have a bristle worm problem in my reef tank: there are at least two
larke worms that are hunting my hermit crabs. Ove time my crabs have
been disapearing and empty shells apearing around the tank and I saw a
3" long worm capture one of them twice already.
The problem is taht I'm not fast enough to catch it with tweezers and
worm trap only traps smaller ones, which I don't have problem with.

The large worm I was didn't look like fire worm. It's purple-pinkish in
color with bristles of the same color. About half of the body is bluish
with same color of bristles.

Is there anything that would hunt them and be reef and fish safe?

Thank you in advance.
Yuriy
