I finally figured out what these things are; I should say I finally found the pic on melevsreef.com It seems getting rid of them isn't the easiest of tasks. I tried siphoning them the other day when I cleaned the tank. I don't think but a few actually made it out of the tank. I was wondering what you might have done to get rid of these things? I'd rather add another fish than use a product since everything says these worms can make your take somewhat toxic when they die. Also, are there any other sites that show pictures for identification of things. I've got another group of worms? that I'm not sure what they are.
