I want to get an axolotl. I have a 20 gallon tank and want to know if I have to cycle it before I get the axolotl. To be clear, I know nothing about cycling or aquariums. I have read a bunch of stuff online, that's the extent of my knowledge. I've read that the tank had to be cycled and that it doesn't. Any axolotl owners out there? Of course I don't want to wait weeks for a tank to cycle, I want to make this impulse but now (lol). I've grasped the concept of a filter, substrate concerns, water temps, diet. Just not sure about this whole cycling thing.
