Fungus?

[Emerson936]

My lil axolotl seems to have injured his arm, he’s been holding it to his side and not using it. About 12 hours after, there’s a while patch on it. Does this look like fungus?

pre-emptive tea baths would help the injury.

it could be bone or coat shed.

make sure he's got clean and cool water.
