i recently bought a jag that is 8in long and he just wont eat is this because hes getting used to the new home or something wrong? im feeding him the hikari gold pellets their large and he takes it in his mouth and spits it out and really doesnt have any disire to try any other fish food i have. should i just give it time or what? i dont wanna just go off and get him rosie reds to eat or some kind of feeder because i dont want that to be all he eats. what should i do?
