a few months ago i took some to-be-exterminated house mice from behind my stove and took care of them in this tank here. they were four younger mice who cuddled all the time but have since grown into adults and have started fighting more frequently. i am not sure if they are girls or boys, they are super wild so are hard to handle. I would like to make a better stress-free area for the mice but i do not have much money. (i do have more terrariums.) Should i put more hides in there? more bedding? separate them entirely, any advice appreciated 🐭
