Is it normal?

[Kaorte]

All 3 were in tanks by themselves and checked out by a vet before I put them in a tank together,which I did yesterday,except to feed.When they reach about 2 feet or 2.5 feet,they all will have seperate tanks,but these girls are about 14-16 inches(with Carmen at barely 14 inches).They havent shown any aggression and didn't have any problems when I fed them,and showing a good amount of activity at night.But I do check in on them throughout the day,havent noticed any mites so far.I try to keep handling during the day to a minimum,and handle in the evenings or night.

If they are eating regularly then they can't be too stressed. The vet check was a good idea. Every ball python is different. Some cannot tolerate being housed with other snakes, and some don't really care either way.

Honestly, I think you are doing fine. Just up the prey size and the cruising after mealtime should subside.
