The Tailspot Blenny, also known as Ecsenius stigmatura, is a popular saltwater aquarium fish known for its vibrant colors and charming personality. In this comprehensive guide, we will explore various aspects of keeping the Tailspot Blenny in a saltwater aquarium.
The Tailspot Blenny is commonly found in the Western Pacific Ocean, particularly around Indonesia and the Philippines. It inhabits rocky areas and coral reefs, often hiding in crevices and small caves.

These blennies are known for their peaceful nature. They generally get along well with other fish and do not show aggressive behavior towards tankmates.
Male Tailspot Blennies have a distinct elongated first dorsal fin, while females have a shorter and more rounded fin. Additionally, males often sport brighter colors compared to females.
The average lifespan of a Tailspot Blenny in a well-maintained aquarium is around 2-4 years. Proper care, including a balanced diet and appropriate water conditions, can contribute to a longer lifespan.
Diet in Aquariums
The Tailspot Blenny is primarily herbivorous, feeding on various types of marine algae. In an aquarium setting, a varied diet can be provided including high-quality dried seaweed, spirulina flakes, and occasional live or frozen foods like brine shrimp or mysis shrimp.
These blennies appreciate a well-structured aquarium with plenty of hiding places provided by live rock or coral formations. Offering small caves and crevices will help them feel secure and mimic their natural habitat.
Captive Bred Availability
The Tailspot Blenny is available as captive-bred in the aquarium trade. Captive-bred specimens tend to be hardier and have a higher chance of adapting well to aquarium life compared to wild-caught individuals.
Compatibility with Other Fish, Invertebrates, or Corals
