Our little Split Mosaic is a lot less noticeable as a split now. The best way to still see it is by putting a filter on. Just know, a Mosaic Axolotl is a Mosaic whether you see it or not. It means its Chromosomes have gone wacky. It's not like you can fix that or it reverses. Some Mosaics are completely unnoticeable, but it's what happens inside them that makes them a Mosaic Axolotl.
When we say Subtle Mosaic Axolotl it's a visual thing. A Mosaic is a Mosaic no matter how visual or not. Now there are definitely different ways the chromosomes are given to a Mosaic. You can have a Haploid (one set if chromosomes, which can cause them to not make it past hatchling stage unless combined with Diploid and Diploid (two sets of Chromosomes which is also in a standard living being, but as a Mosaic its two sets are placed in different areas), and Triploid, and so on. There is actually no end to this. The placement also can sometimes be seen or not, like a Split Mosaic Axolotl where you can see sometimes one side looking different from the other. Or a Mottled Mosaic Axolotl where it is splotchy all over. Some are only internal Mosaics, meaning you can't see it at all, but their insides have wacky chromosomes. Mosaic Axolotls are a very unique thing of their own. We can't breed for them. Genetics 
is an amazing thing that can baffle the best of us!
