This little dip has decided to host this tube worm. There's a perfectly good carpet nem right next to him, but no. Feather duster worm is where it's at.Well....To be honest,clownfish will host whatever they like.Ive seen them host FrogSpawn/Torches/Shrooms/Candy Cane/Hammer Coral/really just about any thing!I have some of mine living in clay pots!
