Gulper Catfish

Asterophysus batrachus is a freshwater catfish species that is native to South America. It has a large, flattened head with a wide mouth that it uses to swallow its prey whole, giving it the common name Gulper Catfish.

In the wild, Asterophysus batrachus feeds on a variety of prey, including fish, insects, and crustaceans. In captivity, they can be fed a diet of live or frozen foods such as earthworms, shrimp, and small pieces of fish. They may also accept pellet and flake foods.

Sexual dimorphism in Asterophysus batrachus is not well-known.

Breeding and spawning of Asterophysus batrachus is not well-documented in captivity.

Asterophysus batrachus may be susceptible to various diseases that affect freshwater fish, such as bacterial infections, parasitic infections, and fungal infections. Common symptoms of disease may include loss of appetite, lethargy, abnormal swimming behavior, and visible signs of disease such as lesions or discoloration.

Asterophysus batrachus is native to the Amazon River basin in South America.

Asterophysus batrachus is a predatory species that can be aggressive towards smaller fish, and may require a larger aquarium with plenty of hiding places and adequate filtration. It is important to monitor their feeding and behavior to ensure that they are not causing harm to other fish in the aquarium.

When introducing Asterophysus batrachus to a new aquarium, it is important to acclimate them slowly to prevent stress and shock. This can be done by gradually adding small amounts of water from the aquarium to the transport bag over a period of several hours, before finally releasing the fish into the aquarium.
