I noticed an interesting phenomenon. In my first tank, the truck was dominated by bristle worms. My second tank started out with a combination of bristle worms and fire worms. But early on I added a piece of live rock from another tank that contained brittle stars and now my live is completely dominated by brittle Stars. I don't have a problem with either and think they are both normal cleanup crew.
But it is interesting that the brittle stars out competed the bristle worms. Anyone have a similar experience? It seems bristle worms are more common, but do brittle stars tend to out compete them or do they just prefer a certain environment?
