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!
