Thats Bandit she is a leucistic axolotl. Speckles show up on them because they still have the black pigment and can happen regularly but usually with little speckles and mainly on the head and the tops of their backs.
I have juveniles with a promising chance of displaying this pattern up for sale, they came from her relation of some sort, Ariel. Too bad your not in australia, if you have a look in the for sale section on here tho you might be able to find some!
Ok sorry if this is a dumb question, I'm new with Axies lol.. But what color is your Axolotl in your profile picture considered? I just LOVE the ones with the normal coloring but has that pied look haha.. Again sorry if that is a dumb question, I'm just curious!
