Common name: Portenoy's Blenny

General information

Portenoy's Blenny, scientifically known as Ecsenius portenoyi, is a small, colorful fish that is a member of the Blenniidae family. This species is named after Dr. Richard Portenoy in recognition of his contributions to the field of pain management. It is a relatively new addition to the aquarium trade and is appreciated for its vibrant colors and active behavior.

Care

Portenoy's Blenny is a hardy species that adapts well to life in captivity. It requires an aquarium with plenty of live rock for grazing on microalgae and for hiding. This species is known for its peaceful temperament, making it a good candidate for a community tank with non-aggressive tank mates. It is important to maintain stable water conditions and provide a varied diet that includes marine algae and meaty foods.

Reproduction

Like many blennies, Ecsenius portenoyi is oviparous, with the female laying eggs in a secure location within the rockwork or decor. The male then guards and cares for the eggs until they hatch. Breeding Portenoy's Blenny in captivity can be challenging, but it is possible with careful attention to their environmental and nutritional needs.

Habitat

Portenoy's Blenny is found in the Western Pacific Ocean, particularly around Indonesia. It typically inhabits shallow reef environments where it can be seen darting among the coral and rock formations. This species is often found at depths where it can easily access its natural food sources, such as microalgae growing on the substrate.
