Overview: Non-dominant males are very pretty with orange colored fins lined with yellow and a broad orange band below the 2nd dorsal fin. In dominant males, the colors are even more intense.
 
Gobies of the Lentipes genus are beautiful, personable fish that have adapted to a specialized amphidromous lifestyle. Adults live and spawn in freshwater streams which flow to the ocean. The tiny newly hatched larvae are too underdeveloped to be called fry at this stage. These larvae flow downstream to the ocean where they settle into the plankton cloud and feed on microscopic marine organisms. After they have grown and developed enough, the young fish then leave the ocean and continue upstream to their freshwater origins. In order to complete their journey home, the young fish must overcome torrential water currents. Often, they even have to climb waterfalls. Their specially developed pelvic fins form suction cups which, when used in conjunction with their gripping mouths, help them make it through these obstacles. With these adaptations, they are able to make it home and take advantage of pristine rocky stream environments that other fish species simply cannot reach.
