The Ornate Bichir I owned for a week. I couldn't figure out what was happening until I snuck out at night to find him slithering around, quietly nipping at everyone's fins. He'd move to a prime location and wait. Someone would swim by and up he'd go, just fast enough to slice the anal or caudal fin. And I was feeding everyone well. He was just a nocturnal fidgeter, I guess. That's why I only kept him for a week. On retrospect, I should've gotten rid of everyone else and kept him. He only cost me $20 at 12". Now I want a bichir...
