homade growout tanks for catfish. I used two 55 gal. storage containers side by side. I got a cheap in the tank filter that filters about 100 gph, ran an airline and heater to each, and I now have some cheap grow out tanks for when I set up my indoor pond. I plan on growing the catfish to a safe size, and when they are big enough introducing them to my indoor pond(currently in the making) For now they will house some awesome catfish courtesy of The Trust. Let me know what you guys think. I am gonna upgrade the filtration in the future. This setup costed me less than $60 per tank to do.
