Injured Axolotl Help

[Emerson936]

Last nights my axolotls scared each other and got in a quick scuffle. One now has his arm held back to his side and a few white marks on it now. How serious is this? What’s the best way to treat it? Thanks!!

provided the water levels are good and kept cool he should heal fine.
axolotl bones are like cartilage so I doubt there will be a break.
using holtfreters in the water will help heal and also stave of infections and fungus, info here.. Axolotls - Requirements & Water Conditions in Captivity
