ok ive been searching for the ID of this worm everywhere but i cannot find it..

it was about 6 inches long with a red head area about 1/2 inch long with a maw. One night i went to bed and everything was fine the next morning my yellow tang had a hole about 1/8 inch diameter strait though it.. i searched everything in the tank looking for a cause but found nothing.

about a week later another fish had the same.. one night while watching the tank in the dark i saw it and watched where it went but never could catch it.. after it killed 1 more fish i had to dismantle my tank inevitably killing everything... i would really like to find out what this was so when my new tank gets set up i know what region of live rock to be suspicious of.

are you sure it was a worm? Could it have been a mantis shrimp?

Did it look like this?

gryffyn, welcome to TR.

Can you get a picture of this thing?

Dick

That thing sound viscous...Do you think that the fish are dying from another source and the worm is being opportunistic?

no its not a mantis shrimp... it may be that it turns out to be a eunice type worm..i dont have pics i didnt have a camera at the time... and it was the worm attacking the fish i saw him attack the 3rd fish and i tried to catch him at that time but couldnt and that night he killed the fish so i ended up having to purge the rocks which killed all my inverts

uigh....did you find him then?

yeah i eventually got him but am having to start all over again.. so ive come lookin for advice and others know-how.. this place is great..

did you get a picture? What kind of worm do you think it was? I'd be very interested to know what kind of worm would cause such damage to the fish!
