OK, I want an Axolotl tank and I need to know some things. First off, would a 29 or 30 gallon be big enough? I've 20's good for one but other things say I'd need a 40 gallon for two. Either way I want two, I've seen things saying 30 gallons is good for 3 but that's a decision for after I get the first couple, to see if I like them and if I want to spend that much more money. Another question is is what are some cheap brackish plants. I want to spend as little money as possible but I also want the tank to look good and nice. Question number 3 is should I give them a spot to get out of the water. I know they'll dry out out of water for too long but they'd be right there and are amphibians that will grow lungs. And that's it, I'd really appreciate some answers, also I won't get the tank for a while so I have time to contemplate life.
