Barred danio

📖 Overview

Occurs in still pools to swift flowing streams with pebble or boulder substrates, seldom over sand. Has not been found in silted rivulets flowing into mainstream. More sedentary than D. malabaricus. Forms groups of 3-5 individuals slowly moving near the surface. Probably feeds on insects. Aquarium fish exporters voluntarily refrained from collecting this species until it was better understood and bred commercially. Collected in moderate numbers.
