I've just recently moved and I just reset up my 16 gallon nano tank. I brought all my live rock down with me in buckets and I made sure to rinse them before putting them in my tank. I let the rock sit in there for a few days and then added 2 damsels. So far one has died but i'm pretty sure it was because the other was picking on it. My fish are getting sent down to me in a month, and my tank has already been set up for almost three weeks now, is that going to be enough time?
