I have a 12 gallon nano that has been running about 1 yr. pair clowns, 1 fire shrimp, 5 snails, 17 pounds of live rock. I just purchased a 24 gallon nano and want to move everything from 12 into the 24 except the substrate. bought new 30 lb. Argonite. tank is filled and running with PS for about a week now. My question when can I move the LR over all pieces have coral on them except one, and two when can I move fish, and invert over.
