Freshwater Sole

Freshwater Sole (Brachirus selheimi)

A fascinating flatfish that lies buried in the sand with only its eyes visible, the Freshwater Sole is one of the most unusual bottom-dwellers available in the hobby. With its flattened, oval body and both eyes on the upper side, it's a master of camouflage and ambush — a rewarding and characterful addition for aquarists looking for something truly different.
