Description: Larvae of the cleaner gobies are likely identical (described above under E. illecebrosus). Transitional recruits develop two wide dark stripes along the top of the head separated by a thin clear line. The stripes meet behind the head and extend along the base of the dorsal fin fading out before the caudal peduncle. Anterior to the head stripes, the dorsal snout area is uniformly dark, covering most of the area between the eye and the upper jaw. Below the dorsal midline stripe is a prominent lateral clear band outlining a white iridescent stripe (blue in life), running from the dorsal aspect of the eyeball back to the upper half of the tail. The snout has a short extension of the blue stripe forward of the eyes, but there is no meeting of the color across the snout or midline bars or spots of color. Below the light band there is a wide dark stripe running from the eye along the body just below the lateral midline to the caudal fin, widening at the caudal-fin base and then extending out along the lower central caudal-fin rays. Deep to this surface stripe is a broad streak of internal melanophores extending above and below the lateral midline. New recruits develop a "sharknose" appearance, where the tip of the snout extends forward over the upper jaw.
