Common Name: Red neon blue-eye

Species Photo by: Greg Gregory
Description: Pseudomugil luminatus males have a body colour that is generally yellowish tan, yellow orange, or reddish with scales thinly outlined with brown, sometimes silvery white on belly and breast. They have a neon-blue stripe on the uppermost part of the body extending from the rear part of the head to the base of the uppermost caudal-fin rays. Median fins are generally yellowish-tan to pale-orange, variably marked with widely scattered small black spots; the anal and caudal fins generally have fewer spots, and those of the anal fin are mainly confined to the basal half or posteriormost section. The first dorsal fin has a narrow white anterior margin, white colour extending onto elongate fin filament. The caudal fin has prominent white tips on dorsal and ventral lobes; pelvic fins translucent yellowish with elongate orange filament anteriorly. The pectoral fins are mainly translucent with bright yellow or white mark along the upper edge of fin. The snout and upper part of the head is pale greyish to blue grey, usually with a red hue on the opercle due to the underlying red gill filaments and transparent nature of the thin outer covering of scales and bone. The eye pupil is black and iris bright blue. The females' body colour is generally similar to that of the male, although smaller individuals are more yellowish and semitransparent; fins mainly translucent to slightly yellowish, usually without spots.

This species does best in a group of at least 6 with at least an even amount of males and females, with extra females preferred. The males will flare fins at each other in a beautiful show, but never harm each other. Males fins are noticeably larger and more colorful than female's fins. The fins are incredible, with their unique shape and length. They are more prone to sparring than other male Pseudomugil, frequently showing off their fins, but usually only for a brief moment. 10 gallon minimum tank size for their energetic nature.
