ID please some type of worm

I found this in some base rock I purchased and want to know if its safe to put into my display tank. There are a few of them inside the rocks this is the biggest one.

I want to make sure its not going to attack my diamond goby or my big engineer gobies while they sleep in there burrows.

 

bristle worm ok for the tank just watch your skin.Also as they get bigger they just look nasty.

 

Yep Definately Bristleworm. Good Scavenger.

 

awesome thanks, i will let them loose in the tank didn't want them attacking my gobies or fish at night.

How big will they get?

 

saw one of mine come out last night, was about as thick as an ipod charger cord and prob little less than 2" in length, much creepier looking at this size than when they are small

 

They can get quite large. I had one get to be about 1/4 inch in diameterand over 1.5 feet long. They are harmeless, and annoying. The biggest problem with them is they can breed like rabbits and take over the in time but, they are great scavengers and help quite a bit. But if they do get to be too many in your tank you can always put a bristle worm consumer in your tank to help kep the population down. I use a coral banded shrimp. But, I have heard of people using copperband butterflys and sixline wrasses.

 

my 6line is too small to eat the bristle that i saw last night! just gives me creeps thinking about it, next time I see that sucker i'm gonna try to yank him out with tweezers. it's getting too large and gives me the creeps everytime i see it

 

Then you might as well get prepared to remove one very couple months. There is a tiny one just waiting to replace the larger one I can guarantee. It would be nice if everything in the ocean or our tanks was visually appealing but that is not the way it is, live and let live if it's doing no harm, or place it in sump.

 

i would definitely leave the guy alone and let him do his job. if you find these guys breeding like rabbits in your tank, you could be over feeding. the population is partly determined by how much they have to eat.

 

i dont mind their presence, just hearing that they can reproduce quickly just gives me goosebumps, i mean the one last night was a juicy one, way too big for my poor 6line to gobble down. i know i have atleast 4 or 5 that i've seen, none of them this big thats why i was probably going to yank him out if i catch him poking around anymore.
