so i have noticed that the 2 of them the last few days havent been getting along to much, the smaller one use to follow the bigger one around like a shadow but the last few days they have been chillin seperatly and the big one starts chasing the small one (kinda like before) only this time the smaller will stop halfway thru being chased and start fighting back almost and they start kinda fighting with there mouths!
why all of a sudden??
