I've been waiting for these guys to show up on market in my country for years and finally found them. I don't have a macro camera so I can't get any good photos of them but they're neat and interesting to observe.
I have a group of them in my 10gallon tank with neocaridina shrimp, assassin snails and a betta. I'm happy to say that everyone is living peacefully without any issues (although the crabs smacked a couple overly curious shrimp during introduction).
