I put in the $99.99 clean up crew special from swf.com a few months ago and it seems half of them have disappeared(crabs & snails),do they eat each other?,I have never seen any of the fish bother them and should I add more to help control the algea?
All tests are ok, I have a tomato clown, yellow tang,yellow tail damsel,atlantic blue angle and a coral beauty, and I have not seen anybody bother anybody but things keep disappearing.
i like snails, myself, trochus or turbos, trochus are a little more$, but they can upright themselves, to avoid drowning, and algae blenny and or tangs,
personally this is what i use

Snails, conchs, abalone, urchins, bristle worms, all work to keep my reef sparkling clean.
Also a 4" DSB and a refugium with some nice Macro algae for nutirent export works wonders.
