They're my favorite fish. They eat themselves to oblivion, never stop swimming, and don't bother smaller tankmates provided they can't eat them. These are Hampala Macrolepidota ... I'm on the hunt for their cousins, Hampala Dispar. I highly recommend this species. My only gripe is their incredibly slow growth.
I wouldn't mind the slow growth. A lot of my fish aren't exactly the fastest growing fish either. And I really want the macros but I would settle for some dispar if I had the chance. I only have mahseers but I can say the hampalas are definitely one of my favorite barbs. Great video by the way.
