I still think yours is getting used to the tank, give him a week to eat, especially after the injury he just received. Keep up the water changes and raise the temp to around 82-84 and this will help speed up the recovery. Give him a week or so before he eats.
As for mine he eats krill, shrimp, floating pellets, worms and tilapia.
