what is this

[clownfishplace]

I just noticed this little worm like creature in my tank. It's black and wight and about a inch long. I don't know were it came from. Does any know if I should be worred about this? Or just let it be? <_< :wacko

If it is a tube that comes in and out of the rock, maybe a peanut worm. Good to have. If it may have had a little pink as well and about a thousand hair like white legs, probably a bristleworm. some say they are bad to have int eh display tank, but great detrivores in a sump. Do not touch them as the legs are like fibreglass shavings and wil act like painfull slivers.
