A small worn like creature is crawling allover my polyps, what could it be? I cant provide a picture because it is so small even if take a pic it cannot be seen in a picture but all can say is It is like a small worm..
chances are is if u have a bristle worm that is brave enuff to come out and walk around all the time u may have more than one they usually hide there is some debate as to wether they are reef safe i ahve a bunch in my tank and never notice any damage to any of my corals and its all softies ubt if u feel it necessary to remove u can buy bristleworm traps
yes you can buy traps or make one yourself: (take plastic pipe drill some small holes on pipe's side and put some piece of fish/shrimp/squid/mussel inside, works like charm), on the other hand bristleworm paranoids should think about natural predation (marine beta, stenopus.sp , arrow crabs and others) cause these worms reproduce remarkably well in our systems and all systems with live rocks probably have them.
maybe it is good to mention that most brittle worms are harmless to live stock but well desired scavangers that should be pat of the the cleaning crew.. There are however couple of predatory species (species that grow large can eventually cause danger to desirable live stock..)
do not try to catch them with bare hand...................
Sounds like a bristel worm as mentioned above. I actually introduced some to my tank intentionally as they are great for cleaning up detrius. The smaller bristel worms may not hurt you, but the big ones definetly will. Just avoid touching them as mentioned above. If you have some in your tank and know it, be careful when picking up LR because you may grab one.
