Hey Bill! Feraligatr and Krookodile ask here. I managed to stop the fight, but unfortunately I had to do it through force (I am unharmed, but the same can't be said for my tyranitar and dragonite). Thanks to your help, I managed to figure out why they were fighting after they were restrained. It happened to be about a particular doll that my Feraligatr had had for years. Krookadile had stolen and buried it in the sandbox out back, and feraligatr wasn't happy about it. They've made up now!
On the positive side, even though it was at the cost of your well-being as well as that of your tyranitar and dragonite, it’s wonderful to hear that you were able to calm them down and sort them out!
On the negative side, don’t forget to teach your krookodile (if he hasn’t already figured it out, at least!) why it’s a bad idea to steal and bury toys that belong to pokémon with a type advantage against him.
Or, well, at all, but you get what I mean.
