Creating a suitable home and raising a healthy family is traditionally the woman’s job. But … this isn’t always the case in the world of fish.

I am lucky enough to live near an exceptionally healthy population of Eel-tailed catfish (Tandanus tandanus). Tandans were once wide-spread across eastern Australia, but populations have declined dramatically over the past decades mainly due to flow regulation. Near Mackay QLD, the male tandans amaze us each spring with their astonishing engineering efforts, undertaken to impress the fussy females.
