I love them. They're pretty and very active as are the kubotais. And, yes, they're healthy. I got them from the best LFS in my city. When I first put them in the tank it was extremely overgrown with plants. Although I liked that look, I didn't see much of the fish nor were they very active. Once I redid the tank to the way it looks in the picture, they became much more active, so I think they need open swimming space where they can see each other to get the most out of enjoying them. I can recommend either embers or kubotais.
