Allenbatrachus Grunniens

Datasheet

General Description

The ''Allenbatrachus Grunniens'', commonly known as the Freshwater Toadfish, is a species that is relatively common in the aquarium trade, despite the misconception that it is venomous. It possesses dorsal and opercular spines that can puncture the skin, necessitating careful handling during maintenance or relocation. This species can emit audible sounds when disturbed, leading to alternative monikers such as "freshwater lionfish" and "grunting toadfish."

Aquarium Setup

It is essential to note that although the ''Allenbatrachus Grunniens'' is euryhaline, it usually struggles to thrive in freshwater conditions over extended periods (see table). Maintaining water conditions within the parameters of 268-447ppm hardness, a pH range of 7.5-9.0, and a temperature between 23-28°C is crucial for the well-being of this freshwater toadfish.

Behaviour

The ''Allenbatrachus Grunniens'' is an ambush predator that typically conceals itself in substrates, rocks, or corals along shorelines. It feeds on a diet comprising invertebrates and other fishes. Known for its ability to produce sounds when disturbed, this species demonstrates unique behavioral patterns that add to its allure in aquarium settings.

Feeding and Diet

In its natural habitat, the Freshwater Toadfish preys on a variety of invertebrates and small fishes. Mimicking its dietary preferences in captivity is vital for its nutrition and overall health. Offering a diet rich in live or frozen foods, such as small crustaceans and fish, is recommended to meet its nutritional requirements.

Reproduction & Dimorphism

Specific details regarding the reproductive behavior and dimorphism of ''Allenbatrachus Grunniens'' are not provided in the available information.

Habitat and Distribution

The type locality of the Freshwater Toadfish is documented as the "East Indies," with its range extending eastwards from the Ganges River delta in India and Bangladesh to coastal regions of Myanmar, Thailand, Malaysia, Cambodia, Vietnam, and the Philippines. A similar-looking species found in the Western Indian Ocean, previously classified as conspecific with ''A. grunniens'', was designated as ''A. meridionalis'' in 2004.
