I just got done switching over my 30 gallon setup for my oscar to a 90 gallon with megaflow. My buddy did the lighting with 2 2 bulb florescents. My oscar isn't eating his pellets and I can't figure out weather it's because the lights might be too bright and he cant see the food or if it's because I changed the pellets and he doesn't like them. I've seen him eat a few and then immediately spit the whole pellet back out. Is it lighting too bright or food not up to par?
