The elephant-nose polystigma, or Linn's haplochromis, a native of Pacific waters,
is easily confused with a closely related species, N. polystigma (English name:
the polystigma) but has a downwardtilted mouth. The female incubates up to 300 eggs
for 3 weeks; the fry are free-swimming when they reach 1 cm. Size: 20 cm.
