Welcome to Caudata.org hope you have many years of happy 'lottl keeping!
Just a little tip, to err on the side of caution - I see in your pics you have quite small gravel/stones that your axolotl may swallow and cause her some health problems. It is suggested that you either have sand, large enough stones that the axolotl can't swallow, slate tiles, or a bare bottomed tank.
Best wishes,
