Chaca bankanensis, commonly known as the Chaca catfish or the frogmouth catfish, is a species of freshwater catfish native to Southeast Asia, particularly found in Indonesia, Malaysia, and Thailand. This catfish species is known for its unique appearance, characterized by its flattened body and large mouth, resembling that of a frog.

Chaca bankanensis typically inhabits slow-moving or stagnant waters such as swamps, streams, and flooded forests. It prefers areas with dense vegetation where it can hide and ambush prey. This species is nocturnal, meaning it is most active during the night when it hunts for small fish, insects, and crustaceans.

In the aquarium hobby, Chaca bankanensis is occasionally kept by experienced fishkeepers due to its unusual appearance and interesting behavior. However, it requires a spacious tank with plenty of hiding spots, as well as clean, well-oxygenated water. Providing suitable tank mates can be challenging, as Chaca bankanensis may prey on smaller fish.

Overall, the Chaca catfish is a fascinating species appreciated by enthusiasts for its distinctive features and predatory behavior, but it requires specific care and consideration in captivity.
