The Pantherfish is not brilliantly coloured but
is nonetheless characterised by a most striking pattern of blue-black circular spots on a
greyish brown background. A striking feature of this fish is the ludicrously small portion
of the head in relation to the remainder of the body. The chromatic tints of turquoise,
gold and silver refracted by the fins are of indescribable beauty when the fish is caught
at the right angle and the eyes radiate emerald-green male-volence like those of a pagan
idol. However, this baleful expression is counterbalanced by the most comical paddling of
the absurdly large pectoral fins, and so the total impression on the observer is an
amusing rather than fearful one. The Pantherfish will nevertheless quickly eat any animal
small enough to fit in its enormous mouth.
When fishes of this species come to know their owner, they spend less of their time
indulging in the classical grouper activity of lurking and may become quite bold, swimming
almost continuously in the open spaces between corals and rocks. With its outlandishly
large fins fully spread, a good-sized Pantherfish is an impressive sight when swimming
prominently in the aquarium.
