Yes they've been together for a little over a year now. They're both around a foot and putting on more girth than length now, the wolf is thicker, obviously. They fight here and there but that's about it. My tank is pretty chill. Tankmates are bichirs and a sun cat. I got the odoe at about 4" and got the wolf a month or 2 after. Every experience is different. Like HarleyK had the same set up though the size difference was a little different with his wolf having the advantage and his ate the odoe. You just have to try it. My wolf has eaten a lot of tankmates when I first got him and was fattening him up, but once he started taking massivore, he got real fat off it and from there he never touched another tankmate. He won't even eat live, I've tried to buy crustaceans, worms, small fish, he just doesn't eat it no more, however I'm sure if I starve him he'll take live again. But I only feed night crawlers for live now. Only thing my ornate will eat.
