Missing legs, salt bath?

I posted in the Axie free for all, but thought I should post here too. I just got in my two axies, so now I have three! My white axie with black eyes is missing two legs, they look like healthy clean wounds as far as I can tell, but I am wondering if I should give it salt baths? I have my two new ones seperated in the fridge right now in different containers with air flow from air stone and another air pipe. They are both eating, getting them home was very tramatic, but they both seem fine, and look very healthy other than the two missing legs, and it would seem the black one I just noticed has a slightly nibbled tail, but I think he will be fine as it is hardly there. I nearly didn't get them today, and it was my fault as I should have sent an alarm or something, but I am so grateful they are home now safe. My Indiana Axolotl Colony Pellets also came today, and they have already eaten some, and i am trying to teach Mr. Nibbles to eat them, as he hasn't quite figered them out yet, but ate one when I held it for him. Thanks guys

Rheann - I answered your post in free for all.

Also you don't need to add the air stone to their containers. Just keep the water clean and the containers clean.

Thanks Cynthia I posted a reply in the free for all, I still have some further questions. I wil take out the air stone and tube, it seems to just blow them around.
