I haven't finished reading the whole thing yet, but is he eating frozen? From wild caught I imagine this is the first step. From there, try soaking pellets in the juices of frozen food and feeding a mixture, slowly decreasing the amount of frozen and increasing pellets.He is semi-aggressive,, still run and says away from me when I come to the tank,,, Being wild caught I know he is going through a shaping period of being an aquarium fish but I'm ready for him to open up more and shoe more attitude,,, Also, if any of u fellas have any tip on how to get him started on pellets I would appreciate it, he is still not eating
