Yep there certainly are a few that I would never want in my system.
Hermodice carunculata and Eurythoe complanata. H. carunculata is a predatory species feeding on almost any sessile animal it can catch, but having distinct preferences if given an option. In particular they feed on corals, hydrocorals, gorgonians, and anemones. They also have preferences of species within those groups. Another favorite food item of H. carunculata is the Atlantic Carpet anemone, Stoichactis helianthis.
