clean up crew requirements

Just remember most crabs are opurtunistic scavangers...ie if there is no food it will eat anything else.. most of my hemits have developed a taste for snailmeat... In my new 120 I will go with lots of snails like 60 and any crab that survives the change over ( 4-5days of rock cooking) which should be all 10 of them will be left in the tank as well... this is just my opinion that snails are better than crabs and will not prove to be as much a nuissance. others will argue the opposite

but you see hermits will eat all the leftover food that is not eaten by the fish or any decaying matter. where as snails mainly eat alge......... both are benificial.imo
