Though I am also unsure of what this is, I am more inclined on it being Xanthic because of the following factors:
1. Search definition of xanthic, and since xanthic means yellow coloration, I would suppose this has xanthic genes.
2. Based on close visual inspection, the perimeter/edges of the scales do really look very yellow as compared from viewing the fish as a whole, from a distance. (as in pict 3)
3. Based on pict 4, there is obvious patterns on the cheek, something which i dont really observe in Leucistic bichirs.
4. Have done a search on xanthic animals and there are some species that is xanthic, but only display lighter yellow coloration, and since i could not find any pictures of any endi which is even part-xanthic, I dont have any basis for reference, and that a xanthic endi might just look like this one.
what do the others think?
