Paratilapia Polleni refuses to eat!

[inkeys]

Hello,

I have a paratilapia polleni. usually he is a very good eater and eats anything i give him, but recently i decided to try him omega one pellets and he refused to eat them. so i tried feeding him only those pellets for a week and he still would not eat them.

tonight i tried feeding him his old food and he is turning his nose up to it now too! he used to eat this food everyday!

what can i do to get him to eat?

i would greatly appreciate any advice anyone might have for me. thank you

Did anything else change? What is your water temp? Did you do a water change recently? Do you feed live foods?
