CUC recommendations

[smalls383]

I have ended my cycle and have a stable tank except for the nitrates which are about 5/10....trying to get them to 0

I have 6 nerite snails and 6 astrea snails, added 1 week ago...sorry for the wrong spelling....haha

So I would like to get some more snails/crabs/other CUC's for my tank...what would you recommend....I have some brown algea on the sand that I would like to get rid of, any recomendations...

Also, can I get some crabs even though I have no food in the tank besides algea? Thanks all!!

I just keep snails for cleanup. For a 54g system, I might start with 6 cerith, 6 Trochus, and 6 Stomatella. The Astraea will be okay as replacments for the Trochus.

Crabs are predatory, so I avoid them, but the emerald crabs often are fairly safe, at least until they get larger.
