Thanks! I've always had a fascination with predators. The bichir is about 6-7 inches but he's eating well, so hopeful that will change quickly. I was offering feeders when I first got the datnoid, but I have moved away from it to reduce the risk of disease introduction. I feed frozen/thawed shrimp, silversides, massivore, hikari sinking carnivore pellets, hikari cichlid bio-gold, bloodworms, and occasionally earthworms. These fish are very spoiled lol!
