Do I Have Worms?

[tang daddy]

If it's the fan worms with a hard tube depending on colour they generally stay small althoughI got a few pieces of lr with the red/white fanworms they have a white tube inbedded in the lr they keep growing and are alot more noticable then when I first aquired them.
Usually reef safe fishes leave them alone however there are a few fishes that do like fan worms like a tang.
