These critters are so cool! To put it simply, they're large freshwater sea monkeys, and if your familiar with triops you have a good idea of how to raise these. I found a packet I had from forever ago, and unfortunately none hatched but it got my mind back on to how truly amazing these things are. They live in pools that dry up, and like annual killies, have a lifespan that matches. I'd post pics if I had any, but I don't yet. However, once it warms up a bit I'll be getting some beaver tail fairy shrimp and I can't wait! Just wanted to share in case I could drag anyone else along for the ride lol.
