is rarer in aquarium imports.The
main differences are the lateral body plates of the
caudal peduncle in A. cataphractus tend to
meet above and below (except the last one), whereas
in A. cataphractus the last four or five
pairs are separated. A. spinosissimus also
has a broader and spinier humeral process. and
A. cataphractus also tends to be a more slimmer
fish. Aquarium Care: No problem inhabitants
of a medium to large community aquarium. Provide plenty
of hiding places for this species as they are crepuscular
catfishes and will very rarely venture out in daylight
or bright light. Their fins can inflict a nasty wound
if you handle them the wrong way as they can clamp
their pectoral fins around the fingers. They can omit
croaking sounds, hence the common name, which is applied
by them rotating their pectoral spines in their sockets.
Diet: Sinking tablet food, worm foods
and most aquarium fare.
