I agree alto. These fish have always fascinated me ever since I first got in to fish keeping about a 100 years ago, it's one of the reasons this tank caught my eye. I think they were classified as genus Chanda back then.
Indeed fascinating fish.. They also caught my eye a few years back for my asian themed scape.
I actualy don't realy remember but i think they didn't come cheap. And grow to big for my tank.. All tho regularly available from the importer not a fish to find easily in the lfs. And i'm always reluctand to order lifestock i have no experience with or never seen for real.
