I had to artificially establish Lightning as above Stomps, because Stomps wouldn't stop trying to assert himself. The fights he would instigate got very, very ugly. I no longer let either of them sleep in my bed, and I only let Lightning sit in my lap. I feed Lightning first, and I feed them in separate rooms. I've kept to this for about 7 years now, and we've only had one major fight in that time. I guess it's up to you to decide whether they will establish a pecking order and things will settle down. I've known pairs that never quit going after each other (it's usually one that's the instigator). And obviously others have had different experiences. Good luck.
