my live rocks are starting to look a little shabby. i just changed my 90gal from a FO. i threw in about 70-80lbs live rock and a 4"sand bed. it has angels a puffer and a humma humma trigger.
With a Puffer and a Trigger in the tank, the choices in clean-up crews is minimal! I keep a couple of those monster Turbo snails(golf ball size) in with my Puffer. I also have a HUGE Hermit crab that luckily eats algae
IME smaller snails and crabs make an expensive snack
Look into the "Giant Tulip Snail" It's about $20, and won't work ina coral tank cause it would disrupt the corals. This guy is huge, about the size of softball. Make sure your rockwork is stable, as he can disrupt that too.
