New Danio species

By Leonard Ho - Posted Aug 04, 2015 09:00 AM
Danio annulosus is the 25th species of the genus described. Unlike the striped patterns of the zebra danios, D.annulosus has a chain-link pattern. And it's not the only new Danio on the block.

2015 has been a very busy year when it comes to new Danio species from southern Asia (India, Nepal, and Bangladesh).  A remarkable six novel species have been described thus far, already marking 2015 as the most prolific year ever for danio discovery.  The six species are:

  • Danio absconditus
  • Danio annulosus
  • Danio assamila
  • Danio catenatus
  • Danio concatenatus
  • Danio sysphigmatus

 

Five of the six new species share very similar "chain-link" patterns to the newest species, D.annulosus.  Only Danio absconditus, below, differs with a more vertical "tiger-striped" pattern.

Welcome to the family!
