Are they bent backwards like that? Or is she just holding them like that?
You say your axie has a hard time swimming. How about walking?
One of my young axies had some weird toes clumped together. A tank mate ripped them off and they grew back pretty normal. Not sure if that works perfectly on adult axies. When my adult axies lose a limb it grows back kinda freaky. (Freaky like in: toes clumped together, weird shaped feet, extra toes, missing toes, toes on top of another toe, extra limb etc...)
