I have several fleash colored worms around a few of my soft corals. They are around 3 inches long and look almost like a centipede. Are these causing harm to my corals?
sounds like bristle worms. usually harmless but i have read somewhere in quantity they can do some damage to corals.
If you have a lot of them you may be overfeeding. They eat uneated food in your tank and can multiply quickly. They are good to have but like Screwloose said-you don't want a lot of them.
