Is a worm farm the easiest possible pet? Looking for extreme low maintenance with ability to be away for weeks at a time. Not optimizing for cuteness - just something cool and naturey. Fish would work but seems high maintenance.

I would not choose worms. I got the whole setup so I could have worm tea for my garden, and they all ESCAPED. like, they hated it there. I don’t know what I did wrong but I still think about it

Sea monkeys? Used to be sold everywhere, I don’t think I’ve seen them sold in stores in years. In any case, they’re low maintenance and probably easy to find online.
