I like my urchin, but they will move poorly attatched frags, and even some fairly well attatched ones..... I have one hermit crab, hes pretty cool but not for everyone. A good mix of snails is big tho, I have a couple turbos, about 15-20 astrea snails, a few of another type that I cant think of right now (I think cerith but not sure, Ill check later), and a nassarius snail.
Well put, i would add a serpent star or brittle star.
IMO buying most clean up crew animals = throwing money away. Don't get me wrong I've had trochus snails that lived for many years and did a wonderful job at eating algae. The problem is when they finally died their replacements only lasted a few months (as well as their replacements). I have had similar experiences with most other CUC members I've tried.
Now, my CUC is mainly hitchhiker species that reproduce (and subsequently maintain a balanced population with their food source). Currently it's made up of mostly stomatella snails, mini brittle stars, bristle worms, and astrina stars. The traditional CUC members I still have are a Scopas tang, 2 money cowries, and a "super tonga" nassarius snail. I certainly still need to clean my glass and perform other maintenance tasks, but at least I'm not continually spending only to end up with more empty CUC shells.
