Bristle worm hunter?

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

Have you actually witnessed any worm capturing live hermit crab ?
Or just saw this worm in the hermit's shell and assumed it killed your hermit ?

From what I have read about them, they are rather scavengers
and not active hunters... They feed on decaying carcases only...
Crabs are usually strong enough to eat worms on its own if allowed.

Leave the worms alone !!!
They are beneficial. Only get rid of them if there are more worms than
sand.
They do get big and ugly but they clean up the mess not make it.
They freak me out !

Arrow crabs and 6 line wrasse snack on them.
However they will not be your solution to a population explosion.

Wrasse works good -

TheRock,
I'm not crazzy about eradicating bristle worm and their apperance
doesn't bother me, but I want to get the "boa" out of my aquarium.
I can't say that I have an explosion of population, but I can can see
some worms going about their business.
I'm not feeding my tank at all (at least not in last 5-6 months), so
cutting back on feeding will not fix it either.

Thanks
Yuriy

You dont feed your tank?

How do your fish survive?

Michael,
The way I run my tank is somewhat controversialm but...
I do very few water changes (every three to four months about 10%
I have only a few fish and a LOT of LR in the tank and the sump
(doubles up as a refugium).
Yellow tang and tri-color blenny eat mostly algae, Mandain eats ...posd
and clowns do pretty good on other critters.
I'vebeen watching my tank at night and there is a lot of "food" in the
column, and since refugium is on opposite cycle, a lot of things end up
in the tank during the day too.
I'm watching them very closely and they look well fed and groomed.

Regards
Yuriy

Pszemol,
Yes, I have actually witnessed one capturing a crab. The worm was about
2.5-3" long and 1/4" or so in diameter (the visible part at least).
Yesterday it was "siffing" the san and came acrost a crab that fell on
it's back. Fro what I saw it grabbed the crab and retracted to its
hole.
On previous ocasion I just was one in the shell, not the actuala
attach, so I assumed taht crab had just died from natural causes.

Thank you
Yuriy

Worm draged hermit crab WITH CRAB'S SHELL ?

Yes
Again, that worm is HUGE. When stretched to 3" it was still almost as
thick as a pansil (around 1/4") and the head was even thicker (but
flat).

BTW, sorry for my spelling. I'm using google for posting and there is
no spell check (and I need it bad)
