Naaahh, its a CB endli, considering where it from, I wouldn't call it melanistic either. Its only a darker variant of regular endli, halfway down the tail looks deform. Still, need to see a much better pic...
there are so many possibilities resulted from captive breeding, either platinum, albino, longfinned, and short body, but its also opening the chance of getting poor genetic born bichirs which affect the body shapes, colors, and patterns.
