Tilapia is high in Omega-6 which is not good for you. Pick a fish with Omega-3...it's good for you.

"What may be surprising (and alarming) is that in some fish, including one of the most highly consumed fish in America, farm raised tilapia, omega 3 levels are very low and tilapia omega 6 levels are high, including a particularly inflammation-promoting long-chain omega 6 known as Arachidonic Acid (AA) which orchestrates much of our body's inflammatory response."
