u dont need a green thumb to culture earthworm, just a normal thumb is good enough lol. they are easy enough to maintain. a bucket with cover big enough to hold them. some substrate that's wet to touch but not water logged, i use the old one cleaned out from my frog's tank+some dirt from back yard "without any type chemical", feed them vege scrap left from kitchen. keep it dark, room temperature, and that's it lol!! ...i might type up a more detail one latter when i received my new worms latter tonight or tomorrow.
the rolly polly bugs!! i actually like the name this way. isn't it a lot easier to understand what you are talking about than calling it isopod or woodlice? if it's chemical free wherever you collect them I believe it's fine to just toss them in(correct me if it is not lol!) it's ok if your frog eats them. they work the same way as springtail, cleaning the tank, snack for the frog. which reminds me....I need to go dig some up latter lol.
