so I may have gone a little treat happy and got my oscars hooked on krill. I've noticed they are not eating any pellets at all, it was their main diet since I've had them (over a year). This is something new, they were eating pellets 2 weeks ago, that I remember actually watching them eat pellets. I cut of krill and they haven't done more than poke at a pellet. Its been 2 days and no eats. what is the proper way to go about this? Feed nothing but pellet or should I be offering some krill?
