This unique fish with intriguing anatomy are referred to as Flounder fish because of their flattened and laterally compressed bodies. They are known to inhabit the oceans, freshwater, and brackish water conditions and are typically found on sandy, muddy or silty substrates in bays and estuaries. Sole fish lack pectoral fins and their eyes are found on the left side of the body. They have normal fish-like larvae with eyes present on each side of the head but as the juvenile develops one eye migrates over the top of the head to the other side of the head. As a result, the fish develops a benthic lifestyle resting on its blind side. This fascinating fish will do well in an aquarium if provided with the right environmental conditions. They will spend most of their time on the bottom therefore a sandy substrate is ideal and they will sporadically stick to the sides of the tank.
