Freshwater Frogfish (Antennarius biocellatus)


The lone representative of the marine frog and anglerfish family that is known to venture into brackish to pure freshwater conditions, the ‘freshwater’ frogfish is a unique and fascinating predator rarely seen in the freshwater hobby. Like their saltwater counterparts, they are slow moving, using their elaborate camouflage and lure-like appendage to ambush smaller prey items like crustaceans and smaller fish. In the aquarium, they are best kept in species tanks to ensure they are not outcompeted for food by faster-moving fish and will do best with plenty of rockwork or other cover which they will typically blend into with remarkable skill. Although they are collected in and kept in pure freshwater typically, these fish will do best with the addition of some aquarium salt at minimum and will also adapt with ease to brackish water conditions.
