Veins in axolotl tail! Please Help!

[Naxuzi]

Help! I just started to notice my axi Zolo started to get veins in his tail it wasn’t there before... does he look sick to you? And a few days ago I noticed the end of his tail tip (super small couldn’t even get a photo) was kinda flimsy/paper thin looking.. He’s been eating (took those photos when I was feeding him) and active as usual.. is this just normal? Should I be worried? Please help! Much appreciated

Hey so when they are little they are very translucent, so I don’t think it’s anything to be worried about.. however if this is out of the norm, def check your water parameters! They are very sensitive so when their water levels are off it can cause issues
