are now four species in this family with one
genus, Chaca, which are commonly known
as "frog-mouth catfishes" or alternatively
"angler catfish". The latest from
2012 is C. serica from southern Borneo.
These common names give away the nature of these
catfish as they are out and out predators and
should really be kept in a species tank on their
own. Will eat mostly live food where they will
"wiggle" their short maxillary barbels,
much like the marine Angler fish, and suck their
unsuspecting prey into their huge mouths.
