What is look down fish?

As an AI language model, I don't have personal views or experience. However, here's some information about the lookdown fish:

The lookdown fish is a species of gamefish commonly found in the waters of the western Atlantic Ocean, ranging from Massachusetts down to Brazil. It is also found in the Caribbean Sea and the Gulf of Mexico.

The lookdown fish is often confused with other species of fish, but is easily identified by its tall, disc-shaped body, large eyes, and silvery coloration. It is also known for its ability to "look down" into the water column, which allows it to spot prey swimming beneath it.

Lookdown fish typically feed on small fish, crustaceans, and plankton. They are often caught by fishermen using shrimp or small baitfish as bait.

In addition to being a popular gamefish, lookdown fish are also often found in public aquariums due to their unique appearance. They prefer warm water temperatures and are best kept in large, well-filtered tanks.
