Thanks soggy.
My CUC list:
2x Nassarius (to begin with)
1x Turbo snail (later on)
.

Is 1 CUC per gallon guide sound? So 24g should have about 20 CUC thereabout?
Are shrimps any good as CUC? Hermit crabs?
Also I find it strange that in fresh water when it comes to clean up crew shrimps are the best clean up crew, but when it comes to marine the CUC are dominated by snails and crabs. And man the marine shrimps are huge (compared to the fw counterpart)!
