During its orange-yellow phase often associated with Pseudanthias squamipinnis. Individuals of Ecsenius midas can change color quickly from when on the 
bottom to swimming in open water to match the colors of the fishes they mix with. Forms pairs during courtship and spawning. Eggs are demersal, attaching to 
the substrate via a pedestal. Larvae are planktonic, often found in shallow, coastal waters.
