Axolotls?

I'm new to this site. I'm preparing my tank(a little over 10 gallons) for one axolotl. It's been running-Without any creatures-for about four weeks. I have a filter (does not cause much disturbance in water), a thermometer (Temperature is at 64 degrees Fahrenheit), the water has been tested and is stable at the moment, and I have recently added fine sand, which has settled nicely, and I also bought frozen bloodworms(I know I should be feeding it earthworms, but I feel like I should wait until I have the axolotl and test it's reaction to bloodworms before I obtain those.) I came here because although I have done quite a bit of research by myself, I would feel incredibly guilty if such a fascinating creature became stressed or sickly. So really, my reason for posting this was to ask somebody experienced in axolotl care if I am missing anything. Thank you for reading!:happy:
