I agree with Matt about the fish club, I just got a 125gal from one of our members for $75, 18 fish from Matt's and my box swap, for a share of shipping, and most new fish come from members.
I also unplug most heaters in summer, if the tanks have any heaters at all, and don't light tanks unless they are planted, (and then with DIY LEDs), almost all my filters are DIY and work much better than any store bought kind.
My most expensive energy usage is from pumps, it takes 4 (2000+gph each) pumps to run the indoor tanks, on 4 sumps.
And I also feed worms from the garden, mosquito larvae from rain barrels, in my vegetarian fish get dandelions and other weeds from the garden, and duck weed and algae from the pond.
I have about 1500 gallons in tanks in my fishroom, and a 1000+ gallon pond in the back yard.
