Tank size

[Guydyon]

Hi, I have three axies in a way too little tank (90x30x30 cm), and obviously I am having a hard time controling the N cycle. I want to buy them a new house and a new friend, or two. Now, how big a tank should I need for 4 axies? How about for 5?
Thanks for your replies, I promise I will give them a better house soon.

A 122x33x51cm tank would be adequate for 4 axolotls. The general rule of thumb is 30cm of floor space for each axolotl.
