Axolotl has a white spot.

So, I'm new to this website and I had a question, I bought my axolotl here in Las Vegas about two months ago and decided he was too hard to take care of so I took him back to the pet store and a couple weeks later I wanted to see if he was still there and he was, under a heat lamp, when I put my hand to the glass it was way toooooo warm. So of course I went to complain to the dude, telling him how the axolotls were dying and literally one of the axolotls has no gills and his skin was peeling, they refused to work with me on a price for the remaining axolotls so I had to buy them both full price and unfortunately one didn't make it, I'll insert pictures of them both. Also, when I first got them I gave them both organic tea baths because I heard that helped with fungus. So that was just the back story, it might help to what my issue is today, so I've had the other axolotl in an under the bed sterlite contained which is pretty long and wide and he's kept next to a window a/c which keeps him at 62 degrees F. (Waiting for my tank to cycle, I've been doing 100% water changes for a month with declorinated tap water using reptisafe)He's been doing well for the most part but I noticed that on the tip of a piece of his gill there's a white dot and I don't know if I should be worried.

The first thumbnail was of the one that passed, and the rest are of the same axolotl, with the skinniest version being the first day I received him.

You really save him big time and he looks thousand time better :happy: bravo! In my opinion a white dot might be a small fungus since you keep him in constant water change unlike tank environment. I usually use small amount of the aquarium salt to boost his immune system to fight against it ( not table salt or any other clear rock salt that most people mistaking it for) and Catappa leaf soak along with him.

I would report that store to your local animal welfare authority. The image of the first Axolotl is disgusting and they should be held accountable for their actions.

Well done for saving the other though
