Hey PinkSkullCity, glad to hear your getting into the axolotl craze!
I was thinking, if you don't have some sort of restriction preventing you from doing so, ( space- no stand, whatever :happy: ) you should just plonk your little monster into the 30 gallon tank and be done with it.
More space for your growing axie, you wont have to change it once she out-grows it, plus; with more water volume you get a more stable environment- temperature and your nitrogen cycle being the main factors I am talking about there.
Of course you have probably thought of all this and there is something preventing you from doing so!
So, sorry for stating the obvious if that's what I've gone and done here.
Hope you enjoy your axolotl as much as I do mine!
Best wishes,
Rhys.
