Thanks guys. I have sterbai cories, so I'm glad to hear the bigger guys won't decimate the shrimp either. I'm fine with some disappearing as long as the colony still grows. The cories should stay nice and plump. I'll give it a try, if the shrimp population seems stagnant, I can always move the cories out if needed.
Becca - I have a group of about 6 of the aspidoras in a different tank, but I appreciate the offer. I think a group of 18 would make for a busy tank.
