The other night I noticed what I think may be a tube worm. It's about and inch long and very skinny and has some red fethers that come out and move around. I noticed them moving and going in and out of the tube while I was cleaning the tank. There are some other tube I can see but none of them have any red fethers, yet. I was wondering if they are tube worms what is the best way to take care of them. What do they eat, lighting, and things like that. I would like to see fethers in all the other tubes too.
