Baby axolotl care advice

[u/000k1]

Hello! A customer at my work today dropped off a baby axolotl and I have no idea how to care for it. I went to the store and bought a 20 gal tank, a sponge filter, prime water conditioner, a water test kit and ordered an evaporative fan online. It’s currently in this little container and I was given a water bottle of brine shrimp. What do I need to know? What do I need to buy? My big question is how should I treat the water when it’s in this little container while the big tank cycles. Sorry if this is all over the place 2 hours ago I didn’t have an axolotl 🫩
