My experience of these fish (over about ten years) is that they are easy to keep, shy, hardy, peaceful, and very long lived (I gave mine away after 10 years!). Favourite food in aquaria is frozen bloodworm. Supplement with earthworms, river shrimps, brine shrimp, etc. No need for live feeder fish.
Don't keep them with aggressive tankmates (like cichlids) but you can mix them safely with large tetras, e.g., congo tetras. They need a planted aquarium if you want them to swim in the open. Floating plants are the idea (e.g. hornwort) supplemented with a few bushes of Java fern. Neither of these plants needs much light or any substrate, so life couldn't be easier.
Cheers,
