So I am getting a 75 gallon tank In the near future. I have a 36 gallon bowfront tank with 5 fish and corals including; kenya tree, zoas, hammer coral,gsp, and button polyops. It has a deep sandbed and good amount of live rock 30-50lbs. So I've only had it for 3 months but it's a mature tank. As it was only broken down for 1hour and then reset up(was up for a year before I bought it). Anyways should i keep this tank when I get my big one and let it mature as a reef tank with new corals? Or switch all livestock to the new tank?
