Physical appearance
The ocellated dorsal fin is the most attractive attribute. The back is pale olive, becoming silvery toward the belly. A fine, black line runs from the snout, across the eye to the end of the gill cover, then thickens to a wide band along the body, which suggests its common name, the half-banded pyrrulina. Other fins show blushes of red.[4]
In captivity
A mature male has a more elongated upper caudal fin lobe than the mature female.[4] No record exists of breeding this species in captivity, but the feat is believed possible. The species is not attractive enough to warrant a thorough and intensive effort at breeding, yet with the great contrast of breeding habits in this family it might be interesting to try to induce them to spawn in captivity.[4]
