Anyone else seen their bichir do death rolls? I'll throw big chunks of krill in the tank and the only ones that do it are the buettikoferis. The others just grab and yank, but it's a trip when those little buetts go into the roll. My friends' comin down with some bangin video equipment next month, and I hope I can get some film (er.... binary code) of them in action. Is is a specific thing as I've seen, or do all types do it?
