I currently have a 14 gallon fish tank that I want to upgrade to a 29 gallon. My question is, if I were to drain the 14 gallon into the 29 gallon would I still have to wait for the bacteria to form, or would I be able to put the fish in right away (being that this procedure would replicate a 50% water change)? Also I have one more question, in my current 30 gallon I have two 3" cichlids an albino bumblebee (I think) and a electric yellow lab, would it be alright if I were to place maybe 4- 1" cichlids (2- female bumblebees & 2- female labs) in the tank with them, I formed a lot of caves and such.
