Flounder Fish

Flounder *Paralichthys* spp.

Flounder, belonging to the genus *Paralichthys*, are fascinating and unique flatfish that can be a captivating addition to a large, species-specific aquarium. Their remarkable camouflage abilities and intriguing hunting behavior make them a point of interest for experienced aquarists.

A minimum of a 180 gallon tank with a deep sand bed is recommended to provide ample space for the Flounder to bury itself and move around. The tank should be designed to mimic a sandy or muddy bottom environment. Due to their predatory nature, Flounder are not suitable for reef tanks or community tanks with smaller fish or invertebrates. They will readily consume any tankmates they can fit in their mouth.

Flounder are ambush predators and require a diet of meaty foods. They should be fed a variety of fresh or frozen seafood such as silversides, shrimp, squid, and small feeder fish (use sparingly and ensure they are disease-free). They may also accept sinking pellets designed for carnivorous fish.

In a home aquarium, Flounder can grow quite large, potentially reaching lengths of 12 inches or more depending on the specific species and tank conditions. They are not typically bred in captivity. There are no readily distinguishable external differences between males and females.
