Do axolotls like clutter?

[Sleepylotls95]

Someone told me my 20g low is too cluttered for my one axolot to move about. Which I said he was wrong. He moves about quite fine and I see him walking around and more active at night. Besides the little activity he has always done, he doesn't move much regardless of what i have in there. (Light only on for show).

I think a bit of clutter is good for them, keeps them sharp. Your tank doesn't too cluttered at all.

Having said that, I know some axolotls like a good "walking path": a long, straight, unobstructed line to go for a hike.
You could move the stone near the front of the tank somewhere else, so you have a straight line at the front glass; see if the axolotl uses that area as a highway or not.
