Thanks for the advice. I will get a second water bottle and food dish tomorrow. I have been watching them ever since the fight and they have been getting along fine. The water bottle works just fine. I can see the air bubbles in it when they drink out of it.
I hadn't changed the water in 2 days...
I just bought 2 chins from the pet store a couple of days ago. They are both males. The two were kept in the same cage at the pet store. I'm not sure how long they were together at the store. I have had them in the same cage since I got them and everything has been fine. They seem to be friends...
