Thanks for input guys. The reason why I am asking, is because my Emperor has stop eating for the past week. I have him for about two months now. He's been eating well for a while, until last week. He was eating Mysis,Blood worms,cyclops and spectrum, all soaked in Garlic, Zoe and Seclon. I did had problems with my Nitrate, its down now to 10. When I put the foods in, he looks at it and turns away. He does eat algae strips and lettuce. So, do I have a problem here-?
