What kind of fish has a curved mouth?

Many fish have curved mouths! To give you a more specific answer, I need more information.

Can you tell me:

* What type of fish are you interested in? (e.g., freshwater, saltwater, tropical, etc.)

* What is the purpose of the curved mouth? (e.g., feeding on the bottom, catching prey in open water, etc.)

* What size and shape is the curve? (e.g., a slight bend, a pronounced hook, etc.)

With more details, I can help you identify a specific fish with a curved mouth.
