Stock tanks for fish (outside ponds)
625 gal. 8 ft. Round Poly Stock Tank These type stock tanks are well worth the $ you pay for them I have 1 this very size with goldfish in it 17 to be exact & in the coldest winter season we have had so far in 2026 & has held up, I have a pond heater in it that keeps the water from freezing completely over & the gas exchange to escape.

I've raised blue gills & catfish from the lake in these type ponds ...
