Yeah he's got quite a bit of personality. The loaches were really curious about him, I assume because of his size. They would buzz over the top of his head and get as close as they could. He would always cock his head back and stare at them like, 'get the hell away from me.' It was a hilarious dynamic for all parties except for the congicus. Guess he snapped. Its funny because he is the least confrontational fish I have ever owned. He doesn't even care when my Faranah lap nips at him territorially. He just sits there.
