I was searching for clean up critters and am seeing absolutely insane amounts of snails, crabs etc, being recommended for a 150 gallon tank. I just can't imagine 100 crabs, 150 snails, 20 shrimp etc in the tank. I am asking opinions on the types and numbers of critters that should be gotten that would be
a) reef safe
b) safe from each other
c) fish won't eat or be eaten by
TIA
