I've been able to get these in a few times, so I have some experience keeping them. As far as compatibility, you'd stock them just like any other peaceful rasbora or tetra of the same size. I'd classify their care as "moderate"- they aren't terribly difficult to keep, but they are more sensitive than something like the harlequin rasbora. I didn't have any trouble feeding them and they would take anything from golden pearls to small fish pellets to flake, frozen, etc.
