Orange Fish

It sounds like you are trying to identify a type of fish that is commonly found in restaurants in the USA and is referred to as an "orange fish." One possibility is the Pacific red snapper, also known as the red rockfish or Sebastes rockfish. This fish is known for its orange-red color. However, it's worth noting that the use of the term "red snapper" in menus is often misleading and can refer to a variety of different fish, not necessarily the Pacific red snapper.

Another possibility is the salmon, it's a popular fish in the USA and it has a orange-pink colored flesh.

It's always a good idea to ask your server for more information about the fish and its origin when you're in a restaurant. They should be able to provide you with more details about the specific type of fish and where it came from.
