Common name: Saddle coralblenny

General information

The Headstander Blenny, scientifically known as Ecsenius sellifer, is a distinctive and charming fish species popular among reef aquarium enthusiasts. This species is part of the Blenniidae family and is known for its unique behavior of perching on rocks and corals, often in a head-down position, which is how it earned its common name. The Sailfin Blenny is another name it goes by, due to the impressive dorsal fin that resembles a sail when extended.

Care

Headstander Blennies are relatively easy to care for, making them suitable for both beginner and advanced aquarists. They thrive in well-established aquariums with plenty of live rock for grazing and hiding. These blennies are herbivores, primarily feeding on algae, so it's important to maintain a healthy growth of algae within the tank or supplement their diet with algae-based foods.

Reproduction

In the wild, Ecsenius sellifer engages in fascinating reproductive behavior. Males are territorial and will prepare a nesting site to attract females. After spawning, the male takes on the responsibility of guarding the eggs until they hatch. In the aquarium, breeding Headstander Blennies can be challenging, but with the right conditions and a mature pair, it is possible.

Habitat

The Headstander Blenny is found in the Indo-Pacific region, particularly around the reefs and slopes of the Philippines, Indonesia, and the Solomon Islands. They prefer shallow waters where they can easily access algae growth on the substrate and rocks.
