HI Antonio,
Thats definitely a snakeskin but sometimes they take a long time to color up and pattern up.
You can see that here..

In some of my grow out snakeskins from a cross. Do you know the parents strains?
That fish has nice shape and hopefully turns into a nice adult for you. I would love to see more pics of the ones you got and parents.
