Freshwater Lionfish/Toadfish (Allenbatrachus grunniens)


A unique predatory species, the freshwater “lionfish” is actually a species of toadfish found in marine and brackish waters throughout coastal Southeast Asia. A well-camouflaged ambush predator, they lie in wait for unsuspecting smaller fish and can take down fish nearly their own size with their surprisingly large mouths. In the aquarium, they are best kept in at least lightly brackish conditions and certainly benefit from the addition of at least some salt for long term success.
