Common name: Galápagos batfish
General information
The Red-lipped Batfish, known scientifically as Ogcocephalus darwini, is a fascinating and unusual fish species that captures the attention of many aquarists. It is most notable for its bright red lips and unique method of locomotion; instead of swimming, it 'walks' on the ocean floor using its modified pectoral fins. This species is endemic to the Galapagos Islands and is often found at depths where recreational scuba diving occurs, making it a rare but intriguing find for divers and marine enthusiasts.

Care
Caring for a Red-lipped Batfish in a home aquarium is challenging and generally not recommended for beginners. They require a large tank with plenty of open substrate to mimic their natural habitat. A sandy bottom is essential for their unique walking behavior. They are not active swimmers and often rely on camouflage and their 'walking' ability to hunt for food. Their diet in captivity should include a variety of meaty foods such as shrimp, squid, and fish pieces.
Reproduction
Little is known about the reproductive habits of the Red-lipped Batfish in the wild or in captivity. They are not commonly bred in home aquariums, and their mating behaviors remain largely unobserved.
Symbiosis
While not known for any specific symbiotic relationships, the Red-lipped Batfish's unique appearance and behavior can make it a centerpiece in a species-specific display, where its interactions with the environment can be observed without competition from more active fish.
Habitat
The Red-lipped Batfish is found in the marine waters around the Galapagos Islands, typically at depths ranging from 3 to 76 meters (10 to 250 feet). They prefer sandy or rubble substrates where they can use their adapted fins to 'walk' and search for prey.
