Just curious how many crabs people are using for CUC? Can you list how many crabs and your aquarium size? You can list snails if you wish, but I am mainly interested in crab numbers. I looked at the suggested table on LiveAquaria and it seems really high. I have a 120g and currently have like 10 crabs. They suggest for 125g something like 200+ crabs of various types. Seems like a lot to me, but I do have some minor hair algae I'd like help with.
