So Nitro's been getting bigger, off of the Hikari carnivore pellets and shrimp pellets I've been feeding him. He's not as crazy as he used to be, but he's right up at the front of the tank when it's feeding time. He's afraid of my datnoid-my small, shy datnoid-for some odd reason. He's an awesome fish, quickly catching up to the size of my bichir. Attached are some pics. Looking forward to the future!
