Facts about Zebrafish

Among the most hardy and active of aquarium fish, the Zebra danio is easily recognized by its distinctive horizontal stripes. The slim compressed silver-gold body sports blue-purple horizontal stripes running from gill to tail. The body is elongate, its depth 3.4-4.2 times in SL. The eye diameter fits 3 to 3.5 times in head length. There are two pairs of well developed barbels; the rostral barbels are considerably longer than the eye diameter, the maxillary barbels extend beyond half the length of the pectoral fin. Gillrakers number 10 to 13 on the lower arm of the first gill arch. The lateral line is usually absent, incomplete or rudimentary. There are 28 to 30 scales in a longitudinal series, 15 to 16 predorsal scales, and 6-7 scales in the lateral transverse series In addition to the typical form, a long finned variety exists, produced through selective breeding, which is quite popular among professional and recreational aquarists.
