The Tailspot Blenny, Ecsenius stigmatura, has a black and yellow band just below the eye and featuring a black spot on the tail. They are hardy and can be housed with other peaceful fish in a reef tank setting, but may become territorial towards other blennies, gobies or dartfish in smaller tanks.
Blennnies are known for their incredible jumping abilities, so having a tightly secured lid is suggested. Diet should include a variety of mysis shrimp and vitamin enriched brine shrimp as well as spirulina, marine algae, seaweed and algae based foods 2-3 times daily.

The Charming Tailspot Blenny (Ecsenius stigmatura) in Saltwater Marine Aquariums

The Tailspot Blenny (Ecsenius stigmatura) is a charming and delightful addition to saltwater marine aquariums. With its endearing behaviors and unique markings, this species of blenny can add a touch of character and entertainment to any reef environment. Let's explore the Tailspot Blenny's habitat, reef-safe nature, size, lifespan, diet, aquaculture potential, compatibility, suitable tank mates, tank requirements, other common names, and compatible tank mates.


The Tailspot Blenny is native to the Indo-Pacific region, including the Red Sea and the western Pacific Ocean. They inhabit rocky shores, coral-rich areas, and rubble slopes in the wild.

Reef Safe:

The Tailspot Blenny is reef safe and considered peaceful. They are primarily herbivorous and do not harm corals or other invertebrates.

Size and Lifespan:

The Tailspot Blenny is relatively small, reaching about 2.5 to 3 inches (6.5 to 7.5 cm) in length. They can have a lifespan of several years with proper care in a well-maintained aquarium.


The Tailspot Blenny is an herbivore, feeding on algae and marine vegetation in the wild. In captivity, they require a varied diet consisting of high-quality marine algae sheets, spirulina-based pellets, and occasional fresh or frozen vegetables.


The Tailspot Blenny is readily available in the aquarium trade, and some specimens are captive-bred. Captive-bred individuals are preferred for their adaptability and reduced impact on wild populations.


Tailspot Blennies are generally peaceful and can coexist with many tank mates. However, they may become territorial towards other blennies or similar-looking fish.

Suitable Tank Mates:

  • Dottybacks (e.g., Bicolor Dottyback): Some dottyback species can be compatible tank mates, adding color and diversity to the aquarium.
  • Gobies (e.g., Yellow Watchman Goby): Peaceful gobies can cohabitate with Tailspot Blennies, creating an interesting and diverse tank.
  • Anthias (e.g., Square Anthias): Peaceful anthias species can be suitable tank mates, especially in larger aquariums with ample swimming space.
  • Cardinalfish (e.g., Banggai Cardinalfish): Certain cardinalfish species can coexist with Tailspot Blennies, adding movement and beauty to the tank.
  • Fairy Wrasses (e.g., Lubbock's Fairy Wrasse): Peaceful fairy wrasses can cohabitate with Tailspot Blennies, adding movement and color to the aquarium.

Tank Requirements:

The Tailspot Blenny thrives in a well-established aquarium with plenty of live rock and rocky structures for hiding spots and algae growth. Adequate lighting and a healthy algae population are crucial to meet their dietary needs.

Other Common Names:

In addition to the name "Tailspot Blenny" or "Ecsenius stigmatura," this species is also known as the "Tail-spot Combtooth-Blenny" or "Stigma Blenny."

In conclusion, the Tailspot Blenny (Ecsenius stigmatura) is a charming and endearing addition to saltwater marine aquariums. Their unique markings and playful behaviors make them popular among marine enthusiasts. Aquarists can enjoy the character and entertainment of these captivating blennies in their underwater havens by providing them with a suitable environment and compatible tank mates. With proper care and attention, the Tailspot Blenny can thrive and become a focal point of admiration in any saltwater marine aquarium.

Awesome little guy. Has made his home in a large empty shell in the front of the tank. Love watching him pop his head out and run around for a minute and dive back into the shell.

I ordered two. One has an issue from travel but the other is doing fine. They stick next to each other. The stock photo should be updated. They do not look like this but are definitely very cute. They also change colors!

I would agree with the other reviewer that they are super entertaining to watch. Mine likes to hang out in barnacle and explore the area. Not as colorful as the photo, but maybe he/she will get more colorful over time. Loves frozen food and I think eats flake as well. Good at cleaning up the tiny pieces other fish miss.

Reviewed by: Dennis on Sept. 24, 2016

Super entertaining to watch. Mine loves to perch in my zoas and sleep in a old snail shell. I worried it wouldn't see it much, but that is certainly not the case. He/She is always at the front of the tank. Arrived on time, and mostly unstressed, was eating spirulina algae pellets by Day 3.
