Ruby Longfin Fairy Wrasse: The Social Jumper

This fish belongs to the rubriventralis group of Fairy Wrasses, which are characterized by their dramatically long pelvic fins and pennant-like extensions on the dorsal fin of terminal phase males.
Males typically exhibit a brilliant red or orange dorsal region contrasting sharply with a white or pale belly. Their prominent dorsal and anal fins are scarlet red, often with accents of blue, which intensify during display (known as courtship behavior).

The Ruby Longfin Fairy Wrasse is a vibrant addition to my reef tank. The male’s coloration is stunning, especially during the day when the red fins glow under the lights. It’s active and social, which adds energy to the tank. I’ve had it for six months and it’s thriving with no aggression toward other fish.

Beautiful fish with a unique appearance. The long pelvic fins and red dorsal fins stand out. It’s a bit territorial during feeding times, but with proper tank setup and space, it adapts well. I appreciate the color intensity, especially in the evening light.
