I picked these two uros up from a buddy of mines reptile store. They were tank mates in a 30 gal tank. So I figured there wouldn't be any problem with them getting along. But one uro is larger in size than the other, I was just wondering since they are in new surroundings will they start to behave different towards one another I have had them for about 1 1/2 weeks. They seem to get along well there is no fighting over food but the smaller one eats alot more than the bigger one but the bigger one does eat. What behaviour should as a sign that they should be seperated if need be. heres a pic tiger is the large one closest to the camera and sarge is the smaller one on the rock. Any help would be greatly appreciated.
