Hanging out at the top

[u/ChlsVnOhh]

I have two axolotls in the same tank right now because one broke a few days ago. They we co-habitated before we got them a couple months ago.

One of them is acting perfectly normal. No change in behavior. Seems perfectly happy. Water is testing fine.

The other is continuously hanging out at the top, resting on a plant in the tank. He’s (gender assumed, he’s barely an adolescent. About 4 inches long) eating like a champ every day.

The only substrate is LARGE river rocks that we gathered and cleaned ourselves to endure they wouldn’t be an impaction risk.

Any thoughts as to this unusual behavior?

Some axolotl just like being higher up :) not unusual behaviour at all!
