Tail Injury or Infection?

[Z-One]

I have recently rehomed an adult axolotl and moved him into a new tank. The tank has a chiller was was cycled but seems to have crashed as the nitrites tested around 1ppm today.

I moved him to a QT tank that I can change water on daily while I make sure the cycle reestablishes itself. I noticed on his tale these red marks and not sure if injury from moving around some of the new rock caves / some kind of fungus or infection / or potential burn from nitrites? There are a few spots on the tail end and a larger one a little farther up the tail.

To me it looks like red leg. I would definitely go google the symptoms and additional pictures. If it is septicemia you need to get him to a vet right away. Google exotic vets in your area. What the vet told me to do over the phone was to fridge mine (Make sure your fridge temp isn't below 43 degrees f or 5.5 degrees c) until you could get him in. I have had an axolotl for a long time, but I'm quite new to infections and sicknesses in them, so I'm sorry that I can't really be much help

could easily just be an injury, if there are no other symptoms and no other redness then I would just keep an eye on it
