Any Problems?

[Ambulans Piscis]

I just got my axolotl a few days ago and I just wanted to know if they are okay. It's a little under 6 months and about 3 and 1/2 ish inches. I did not see any signs of anything wrong but I thought I would ask the community just in case. If you see anything please tell me. I will also put photos down below. If they don't work let me know. (the spot on the last one is light)

That's very small for that age. How much do you know about its history?

Those are very tiny for being that old, they look more like 2-3 months old.
