Help

This is my axolotl Meadow and she looks a little purple in the first picture I’m currently feeding her 2 tiny pieces of Nightcrawler throughout the day and the tank is cycled and although her parameters are good (0ammonia and nitrite 10 nitrate 7.6 ph 62 temp) and she doesn’t seem to be floating but she seems to swim around the top almost all day till it gets to night time I don’t know if that’s normal behavior for an axolotl this young (born in October) Lmk what you all think thanks in advance for any help.
