To keep it short, his buddy died about 6 months ago, and he's be acting up ever since. I've gotten some smaller ones since they need groups, but he barely seems to notice them and is always surfing with his reflection on the glass. He and his buddy were in the 5-7" range when the smaller of the two died, he is now coming up on 9-10" while the newer ones are still ~4". Is there anything I can do to help? It's so sad to see him still missing his friend like this. Do you think he'll settle down as the others get bigger?
