Ball pythons acting funny.

Madison and Nergal keep trying to get out of their individual tanks. They lift themselves all the way to the top of the tank, trying to push the lid off. They do this all day and all night, and almost never go into their hides anymore.
This started about three days ago, after I put them back into their tanks when Max and I had been holding them both together. They kind of sniffed eachother and were slithering around but Madison is only like 200-300 grams if that, and so she is too small to breed. :/
I don't know what's up with them. Anyone had their snakes do this? I know they're not sick, as Nergal ate fine (Madison didn't eat today, but she did eat quite a bit last week) and they looked good when I checked their mouths and whatnot.
Any ideas? :/
I'm confused.

I'm by no means an expert but excessive roaming and stretching towards the top are sometimes signs of stress. Check your husbandry.

If you just changed their enclosures, they have to re-adjust and acclimate again.
