Pictus Blenny Care Guide


The Pictus Blenny (Ecsenius pictusi) is a fascinating and unique addition to saltwater marine aquariums. In this comprehensive product description, we will provide you with all the essential information you need to know about keeping this species in your aquarium.


Habitat of the Pictus Blenny


The Pictus Blenny, hailing from the Indo-Pacific region, is commonly found in reef-associated environments. Its natural habitat comprises shallow, rocky areas with plenty of crevices, which it uses for shelter and foraging. These blennies inhabit coral reefs, often taking refuge in small holes and rocky outcrops.


Reef Compatibility of the Pictus Blenny


The Pictus Blenny is generally considered reef-safe, making it a suitable choice for reef aquariums. They are not known to harm corals or other invertebrates, making them a compatible option for mixed-reef setups.


Size and Lifespan of the Pictus Blenny


In captivity, Pictus Blennies typically reach a size of 2 to 3 inches (5 to 7.5 cm) when fully grown. Proper care can extend their lifespan to 2-4 years or even longer.


Diet in Captivity for the Pictus Blenny


These blennies are omnivorous, feeding on a diet that includes a variety of small crustaceans, zooplankton, and algae in their natural habitat. In captivity, they readily accept high-quality pellet or flake foods and live or frozen offerings such as brine and mysis shrimp. A varied diet is essential to ensure their overall health.


Aquacultured Availability of the Pictus Blenny


Pictus Blennies are occasionally available as aquacultured specimens, but their availability can vary. When aquacultured specimens are available, they are a more sustainable choice for your aquarium, as they are not collected from the wild.


Compatibility with Other Fish and Invertebrates


The Pictus Blenny is generally peaceful and can coexist with other fish and invertebrates in your marine aquarium. They are not aggressive towards tank mates and can be kept with other peaceful fish and invertebrates.


Sexual Dimorphism of the Pictus Blenny


These blennies do not exhibit pronounced sexual dimorphism, which means it can be challenging to differentiate males from females based on their physical characteristics.

As they mature, their coloration may become less intense, and they may exhibit a more subdued, cryptic appearance with a mottled pattern.

Very animated. So much fun to watch. Its face reminds me of the crab in the song "Shiny" in the movie Moana. Gets along well with all the other fish in my nano tank.
