If tilapia is a bottom feeder how it kosher?

The concept of a fish being a "bottom feeder" is not a kosher consideration.

Here's why:

* Kosher Laws Focus on Fins and Scales: Jewish dietary laws (Kashrut) only specify that a fish must have fins and scales to be considered kosher. This is the defining characteristic, not where it lives or what it eats.

* Tilapia Meets the Criteria: Tilapia has both fins and scales, making it kosher according to Jewish law.

Therefore, the fact that tilapia might be a bottom feeder doesn't affect its kosher status.
