General information

Ecsenius collettei, commonly known as Collette's Blenny, is a small, colorful fish that is a member of the Blenniidae family. This species is named after the ichthyologist Bruce Collette. It is not as commonly found in the aquarium trade as some other blennies, but it can make a unique and interesting addition to a reef tank.

Collette's Blenny is known for its distinctive coloration and behavior. It has a slender body with a mix of blue and orange hues, and a characteristic black spot on the dorsal fin. This species is relatively peaceful and can be kept with a variety of other fish, as long as they are not overly aggressive.

Care

Collette's Blenny requires a tank with plenty of live rock for grazing on microalgae and hiding. They are herbivores and should be provided with a diet that includes marine algae and vegetable-based foods. They are generally hardy and can adapt to a range of water conditions, but stable water quality is important to keep them healthy.

Reproduction

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

Habitat

Ecsenius collettei is found in the Western Pacific, from Indonesia to the Solomon Islands, and north to the Ryukyu Islands. They inhabit shallow coral reefs and lagoons, often seen perching on coral branches or rock outcroppings. They are adept at blending into their surroundings, which helps them avoid predators.
