Batfish

6 species

Batfish are an intriguing and unique addition to a saltwater aquarium, known for their distinctive, almost bat-like appearance. These fish belong to the family Ephippidae and are characterized by their tall, laterally compressed bodies and elongated dorsal and anal fins, which give them a striking silhouette. Juvenile batfish often exhibit different coloration and patterns compared to their adult counterparts, which can make them an interesting species to observe as they mature.

One of the most popular species kept by hobbyists is the Platax pinnatus, known for its dramatic black body with bright orange or yellow margins as juvenile. However, batfish can be quite challenging to keep due to their specific care requirements. They need a large aquarium with plenty of swimming space, as they can grow quite large—up to 60 cm (24 inches) in some cases. Additionally, they require pristine water conditions and a varied diet to thrive.

Batfish are generally peaceful and can be kept with other non-aggressive fish. However, their large size and specific needs mean they are best suited for experienced aquarists. They are also known to be prone to stress and may require a period of acclimatization when first introduced to a new tank. Overall, batfish are a captivating species that can add a unique aesthetic to a well-maintained saltwater aquarium.
