Hi Penny, I
m pretty new here myself but Ive found so much information and resources here for help.
I would start looking at
Axolotls: The Fascinating Mexican Axolotl and the Tiger Salamander
there is lots of information under the housing and requirements pages.
I also found the Axolotl sub-forum 'tank set ups etc' a great read to research what is safe and not safe for your tank.
For me the must haves after obtaining a tank:
i) Filter (and cycling took a few weeks and constant tests!)
ii)API master freshwater test kit (Other kits may be good - but I like this one)
iii)thermometer
iv)cooler if needed (i use the room aircon)
v)the 'vet fund' - household kitty just incase the worse happens and we need to bring new gilled-children to the vet, incase filter packs it in, to supply food if worms go MIA etc..
and this was even before I got to thinking about rocks, hides, substrate, siphons, food etc!
There is so much information out there, but to me axolotl.org is a great and reliable source to start with.
all the best with your research!
