Glad he is still doing well. Mine was always hanging out with female flames.
I feed mine mysis (large and small) Formula 1 and 2, a "green" food mixture, brine, Spectrum pellets (I let them soak in Vitachem and Selcon) a variety of flake foods such as OSI, HBH, veggie flakes, cyclopezee, Arctic pods, also some squid and clams. Some of them also eat small pieces of Nori floating in the tank.
