The Flounder, also known as Plate Fish or Peacock Flounder, is laterally compressed and lays on its side on the bottom of the ocean or aquarium. Early in development, both eyes migrate to the left or right side, usually the left. The Flounder has a dull color with occasional light blue spotting. This allows it to lay in the sand, where the dull colors blend in making it very hard to see.

It requires a 125 gallon or larger aquarium with a sandy bottom which will allow it to blend in and change positions. It will eat most any invertebrate or small fish that come within its vicinity.

The diet should consist of chopped marine meats.

Approximate Purchase Size: Small: 1" to 2"; Medium: 2" to 3" Large; 3" to 5"; XLarge 5" and Larger

Customer Testimonials

David Y Yorba Linda , CA
I have a lot more expensive fish, but the Flounder is one of my favorites. It's an attention getter, because your guests never know his existence until you drop in some food. This guy swims up to catch his food. It's quite a sight to see a flat white fish gracefully and quickly swim in the water and against the rocks to catch his food. He eats everything - chopped fish, squid, shrimp, and beef heart.

It's one thing to fish for these elusive side sliders. You get a certain swell of "Oh WOW" just watching them feed in their natural habitat. They are the masters of patience and the definition of still hunters. Having one as a pet just makes you love them that much more.
