Freshwater Toadfish (Allenbatrachus grunniens) CareSheet

The freshwater "Grunting toadfish" is really a type of toadfish found in marine and brackish areas across coastal Southeast Asia, making it a unique predatory species. They are a well-camouflaged ambush predator that waits for unwary smaller fish, and their remarkably huge jaws may take down fish almost their own size. They do best in at least mildly brackish conditions in the aquarium, and they definitely benefit from the addition of at least some salt for long-term success.
