I am trying to find good info on this. Tilapia are WARM WATER FISH!!! They are also good eatin’. They like water at least 80 degrees….but need to avoid what we call here in the South, “A Low Country Boil”. I am planning to build a solar green house and have the 385 gallon tank inside. I am not having much luck finding plans/specs, really anything. Welcome any info.

Perhaps a hybrid–active (pump) and passive (heat transfer)–fish tank would be the better bet.

I love the idea of using a fish tank to help reduce energy bills. However, one has to be very careful, as tanks often need a lot of electricity.

Choosing fish and plants would be a challenge.
