Illness/Sickness: Hurt Axie?

[RAHHHHB]

Hey all,

I just moved my axie to a new tank and while i was moving it I noticed this pink mark behind its hind leg. I'm not sure what this could be and whether I should be worried. The picture is from yesterday (when i moved it) and today it looks less pink and more white but it looks like there is a small transparent tube like thing hanging out (couldn't get a good picture of it). Should I be worried??

Thanks!

I think you need to keep a very close eye on this. Keep your axolotl in cool and clean water, maybe add a dried almond leaf to the water. If you see signs of fungus ( this will look like wispy cotton wool) you may need to do salt baths.
Have you any idea at all what caused this? Does your axolotl share a tank with anything else?
If you can, please add any more photo's of the wound.

I'm not sure what could have caused it. I just noticed yesterday when i was changing tanks. Here is a picture from today. Do you happen to have a picture of what a fungus would look like so i Know what to look out for? Thanks again.

Edit: I forget to add that my axie is the only animal in its tank. Also where should I look for dried almond leaf?
