These two in my tank are several inches in length and live in the live rock, not the sand. I was never concerned about it before, b/c everything I had read said they were harmless. Now after reading what was written on the other thread, I should get them outta there.
I should have been tipped off when I saw one eating through a blue ridge coral and the other trying to catch a snail.
I looked in my tank today to find a huge (at least 6 inches that were visible) bristleworm munching on a dead snail! I've noticed a decline in my zoos lately. I wonder if it's been munching on them too?
I tried to catch it twice but the d@mn thing is really quick and shot back into the live rock. I surely want to get something this big out of my tank for fear of what it might eat and the fact they just REALLY creep me out.
Does anyone have at least a ten inch long bristleworm trap or plans to build one?
Also, what's the difference between a bristleworm and fireworm?
