Floating and rolling on side

One of my juvenile axys is floating on top of the tank constantly. He sort of rolls over to his side at times. He attempts to swim but doesn't go under the water, just paddles around on the top. He's been like this for two days. He's still eating well. The water temp is 66 and I continue to spot clean and do water changes. Is there something I can do or should do to help him?

Sounds like they're just having fun floating and let too much air in! It'll prevent them from staying down in the water, and it's common for juveniles from what I've read. This site explains it better than I can. "Lastly, floating. Axolotls will float just for fun, and often swallow air, and are unable to come down for a while. This can easily be mistaken for constipation. I like to check this by blowing on my floating lotl, to give them a wee fright, and they swim back down. If they can’t stay down, then you can keep an eye on them. They may float a lot, and it is easy to get worried, but sometimes they just like it, especially if the water flow from your filter is low. If you see them constantly unable to stay down, and their back legs keep floating upwards, they might be constipated, and you can try a trip to the fridge if you are worried!" Here's another post on the forum about it, looks like if it's caused by the air, you should fridge it to help get rid of the gas!
