The current tank is just a test for a possible larger future setup, 2x1.5x1.5 12mm acrylic tank with a Daeil 1/7 Chiller.
Electric bill has risen significantly but am unsure how much of it is due to the coldwater tank, as I've set up 2 large freshwater tanks in the same month.
As for livestock, at the moment my fish (Blue Devil & Garibaldi) were both bought locally without specially being imported. What fish/inverts are you looking at?
