Thanks. Iknow it hard to get an id from a pic but it is a hitch hiker and hI had no idea were to start looking. I do believe it is a type of porites. yes that is a brissle worm, there are alot of them in the tank. Should i try to get rid of them? They dont seem to bother anything. thanks
Bristle worms are good at cleaning up detritus, and have had a bad reputation, though unwarrented. If you have a lot of BWs it means there is plenty of food for them to eat, but their numbers will fluxuate with food availability in your system over time. I wouldn't try to get rid of them... especially if you don't see any negetive effects from them. I have a few in my tanks as well and I leave them alone since thet are good little cleaners.
