Common name: Yaeyama blenny

General information

The Yaeyama Blenny, scientifically known as Ecsenius yaeyamaensis, is a small, colorful fish that is a member of the Blenniidae family. This species is named after the Yaeyama Islands where it was first discovered. It is known for its vibrant coloration, typically exhibiting a mix of blue, yellow, and orange hues that can add a splash of color to any reef aquarium.

Care

Yaeyama Blennies are relatively easy to care for, making them suitable for both beginner and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for grazing and hiding. These blennies are herbivores, primarily feeding on algae. Providing a diet that includes marine algae or algae-based foods will help maintain their health and coloration.

Reproduction

Like many blennies, Ecsenius yaeyamaensis is oviparous, with females laying eggs that are then fertilized by the male. The eggs are often attached to the substrate or hidden within the rockwork. Parental care is minimal, and the larvae are planktonic after hatching.

Habitat

The Yaeyama Blenny is native to the Western Pacific, particularly around the Yaeyama Islands and the Ryukyu Archipelago. They are typically found in shallow, coral-rich environments and often inhabit crevices and overhangs within the reef.

Geographical distribution includes the Western Pacific: Yaeyama Islands and the Ryukyu Archipelago.
