really now. how much clean-up crew do you really need.
i see so many markets selling complete "crews" for a 50g and 100g and 150g plus.
why would you really need 1 snail per gallon and 1 crab per 4-5 gallons?
thats alot of stinking stuff.
in my 125 i think i have 4 turbos and 5 margarita snails, 5 nassarius snails 2 small turbin? snails 1 cleaner shrimp, 1 fireshrimp and 1 serpent star, 5 small hermits that will kill anything for a shell! i think the real clean up crew is my bristle worms! i have hundreds of them and they do a fine job!

so again why such a large CUC?
