Hi Neurus
It's still early days before you'll know the exact type of axolotl you have. At this young an age it can go either way - wildtype/leucistic (white with dark eyes) or melanoid. You really won't know until it develops more. There are many types of wildtype colourings, if you check out photo gallery. Predominantly in Australia I notice their wildtypes tend to be light coloured (a caramel or mocha brown, even gold looking ones) whereas in NZ we tend to have the darks coloured - browns/blacks and grey looking wildtypes.
Some of the larvae I currently have that were olive/gold coloured prior to hatching - their colouring has also changed, a few retained the olive colouring, some have become very dark and some are still silver (all with dark eyes), so are more likely to be wildtype. Parents are golden albino and dark wildtype.
