Found these amazing color morphs of Esox Pikes on the internet. I am guessing these are Esox lucius, but it's kind of hard to tell due to the color difference. The first one is the melanistic pike. Pretty sinister looking)))
Leucistic or Golden Pike
I wonder how a northen pike of this amazingly bright color could survive in the wild. Probably wouldn't. And it looks like this Esox pike is living in aquarium.
Finally, an amazing super green northern pike)))
If anyone knows anything about these amazing fish, please let me know. I am curious about them.
