Small bumps on axolotls head and leg

[luquisaurio]

A few days ago, i noticed some small bumps on my baby albino axolotls head and leg. He is acting just fine. The tank is 10 gallons and is housing another baby axolotl, and i have sand as the substrate. Ammonia and nitrates are all in check, and the Ph is around 7.6. the other axolotl does not have those bumps on him.
here are some pictures:

If any one could identify what is happening, it would be mos appreciated.

The images are very blurry. Could you take some clearer pictures?

I can make out what appears to be a lot of little bumps on the skin though

Alright, I will get clearer pictures as soon as i can.

Unfortunately the images still aren't crystal clear and without detail it is very hard to give a proper opinion.

Perhaps it is Gas bubble disease: "Air bubbles under the skin. Can result from supersaturation of the water with gas; prevented by aging tap water before use."

The bumps strated to shrink, and today they are compeletly
Gone.
