I love being gatekeepy about pets bc if someone asks me what it's like to keep like. Mastacembelid eels I will be like don't. not bc they're particularly difficult but they require live food. you can get lucky and they will eventually accept frozen thawed shellfish, but for most of the time you need to be fine with setting up a couple cement mixing tubs that will become your worm bins. for your worms. your hundreds of worms. thousands of worms, ideally. and you need more than one because you don't want to keep exhausting your worms every two months and buying one thousand worms multiple times a year, you're wasting your money. you need one bin that you're actively harvesting from and another bin that you allow the population to grow, and the more eels you're feeding, the more bins you need. I need to set up two more bins and order about 1500 worms this weekend. you also need to care for the worms. you gotta feed them, you gotta keep em moist. not hard, but it's more work, it's extra steps. I love my eels. I don't think other people should just have them willy nilly.
