Species Name:

Ecsenius stigmatura (Spotted Blenny)

General Information:

Ecsenius stigmatura, or the Spotted Blenny, is a small species of blenny native to the Western Pacific Ocean. With their charming personalities and striking appearance, Spotted Blennies make delightful additions to reef aquariums.

Tank Requirements:

  • Tank Size: A minimum tank size of 20 gallons is suitable for a single Spotted Blenny. Larger tanks are recommended for multiple individuals or if you plan to keep other fish species.
  • Water Parameters:
    • Temperature: 72-78°F (22-26°C)
    • pH: 8.1-8.4
    • Salinity: 1.020-1.025
  • Substrate: Fine sand substrate is preferred, as Spotted Blennies like to sift through the sand and may bury themselves for protection.


Ecsenius stigmatura are omnivorous and should be offered a varied diet, including:

  • High-quality marine-based flakes or pellets
  • Frozen or live foods such as brine shrimp, mysis shrimp, and small crustaceans
  • Vegetable matter such as blanched algae or nori sheets

Tank Compatibility:

  • Aggression: Spotted Blennies are generally peaceful towards other tankmates, but they may display territorial behavior towards conspecifics or other blennies of similar appearance.
  • Tankmates: They can be kept with a variety of tankmates, including other peaceful fish species and invertebrates. Avoid housing them with overly aggressive or predatory fish that may harass or prey on them.
  • Reef Compatibility: Spotted Blennies are reef-safe and will not harm corals or other invertebrates. They may even help control algae growth.

Behavior & Temperament:

  • Peaceful: Spotted Blennies are generally peaceful and can be kept in community aquariums with other non-aggressive species.
  • Active: They are active fish that spend much of their time exploring the aquarium, perching on rocks, and observing their surroundings.
  • Burrowing: Spotted Blennies may dig and bury themselves in the substrate, especially when they feel threatened or stressed.

Tank Environment:

  • Rockwork: Provide plenty of live rock formations with caves, crevices, and overhangs for the Spotted Blenny to explore and hide in.
  • Plants: Live rock with algae growth can provide natural grazing opportunities and enrichment for the blenny.
  • Lighting: Moderate lighting is sufficient, as Spotted Blennies are not particularly sensitive to light levels.


  • Water Quality: Regular water testing and maintenance are essential to ensure stable water parameters. Perform regular water changes to maintain water quality and remove excess nutrients.
  • Substrate Care: Stir the sand bed occasionally to prevent anaerobic pockets from forming and to maintain water circulation.
  • Feeding: Offer a varied diet and monitor feeding to ensure all fish in the aquarium are receiving adequate nutrition.

Health Considerations:

  • Quarantine: Quarantine new arrivals before introducing them to the main tank to prevent the spread of diseases.
  • Parasites: Keep an eye out for signs of parasites, such as abnormal behavior or visible signs on the fish's body. Treat promptly if necessary.
  • Stress: Minimize stressors in the aquarium environment to prevent health issues. Provide hiding spots and ensure compatibility with tankmates.


Ecsenius stigmatura, the Spotted Blenny, is a delightful and colorful addition to a reef or fish-only aquarium. With proper care, a suitable tank environment, and a varied diet, they can thrive and become a charming resident in your aquatic community. Remember to provide ample space, appropriate tankmates, and regular maintenance to ensure the health and well-being of your Spotted Blenny.
