This species can be confused
melini but the revealing factor
is the position of the black body stripe on C.
metae which runs over the ridge of the back whereas
in C. melini it breaks and divides into two
over the back and continues to almost the end of the
lower lobe of the caudal fin, in other words it shows
the body colouration on the ridge of the back, while
C. metae, on the ridge of the back, is black.
The difference between C. metae and C.
davidsandsi is that the latter has a broader
black band which covers the ridge of the back, whereas
C. metae has a thinner band and has also
a thinner black band over its eyes, compared to C.
davidsandsi. The latter also has a lighter body
colour. Lineage: Placed in Lineage
9, the "short-snouted" species with the
designated type species: C. punctatus. A
revision in the future would constitute the resurrection
of the genus name Hoplosopma (Agassiz, 1846).
Aquarium Care: Good addition to an
average sized community tank. Purchase at least six
specimens to form a group. Diet:
Adults can be fed the usual good quality flake food,
frozen bloodworm, tablet foods, white and grindal
