Trying. It's super hot lol

Look into raising crickets. I know a lot of people did it from back when I had tarantulas. Folks with a large collection would have cricket colonies in totes. Not sure what kind of fish youre wanting, but I imagine crickets would be good for larger fish like koi.

Steem is a good place to learn about permaculture. Theres a ton of folks here that have really badass setups. I recommend @elfmyselfandi and @brockolopolis. They have a badass piece of land they're working on turning into a permaculture eden. They post about their projects and progress often :)
