Showboating Midas Blennies

A male Ecsenius midas in his nuptial colors.

Fish often exhibit incredible pigments and dramatic behavior when courting the opposite sex. The most recognized example in marine fish is flasher and fairy wrasses, whose males change into colors so remarkably different than their regular state that they look like entirely different species.  For this reason, marine aquarists often keep wrasses in male/female pairs (or harems).

We don’t look at blennies the same way, but our friends at shows us why we should.  Ned and Anna DeLoach document the courtship of Midas blenny.  The male blennies put on incredible shows to attract females into their nesting lairs.  Read more about them at
