Normally aquatic creatures, Hanenbow sometimes use floating leaves to launch themselves out of the water, creating strange sounds and melodies as they bounce off the leaves.
Entire schools of Hanenbow have been known to launch out of the water, one after another. As a leaf is repeatedly hit by flying Hanenbow, it gradually changes color. This also alters the sound made by bouncing Hanenbow. When all the leaves turn red, a flower will bloom. It remains unclear why the Hanenbow display this curious behavior.
