The Sand Flounder is a large-mouthed fish, and is narrow at the base and widens towards the tip, each stimulating a detached segment of the anal fin. It grows a maximum up to 18 inches, and is considered shoal-water flat fish. The Sand Flounder looks lovely, when it raises its eyes over its body for peering and settles down at the bottom. It thrives well in a temperature of 68-78 degree Fahrenheit, and requires a thick sand bed in the tank. The Sand Flounder loves to hide under the sand bed and will be found mostly hiding under it. It is basically a peaceful fish, and does not bother any other reef tank inhabitants, thus making it a coral safe specimen. The Sand Flounder should not be housed with any other predatory fishes, since it is a docile fish.
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.
