Tailspot Blenny

The Tailspot Blenny (Ecsenius stigmatura), also known as the Tail-spot Combtooth-Blenny or Stigma Blenny, is a charming addition to saltwater marine aquariums with its distinctive black and yellow band below the eye and a black spot on the tail. Native to the Indo-Pacific region, including the Red Sea and western Pacific Ocean, they thrive in reef settings and are reef safe, primarily feeding on algae. Growing up to 2.5 to 3 inches, they require a varied diet of mysis shrimp, spirulina, and marine algae. Tailspot Blennies are generally peaceful but may become territorial towards similar species. Compatible tank mates include dottybacks, gobies, anthias, cardinalfish, and fairy wrasses. Tank setups should include plenty of live rock and hiding spots, with a tightly secured lid due to their jumping abilities. Acquiring Tailspot Blennies from reputable sources like Saltwaterfish.com ensures a delightful addition to any saltwater aquarium, providing character and entertainment for years to come.

Size and Lifespan:

The Tailspot Blenny reaches 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.

Tailspot Blennies are widely available in the aquarium trade, with some being bred in captivity. Those that are captive-bred are favored for their ability to adapt and their lesser impact on the wild population.


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

Excellent fish for smaller tanks; but it's a jumper. Lost it in a few days even though the top was 99% covered.

This is the most interesting fish out of all the fish that I got he has three or four little holes in rocks that he inhabits from time to time but he’s normally out and about checking things in the tank and he recognizes me when it’s time to feed beautiful fish

Blenny was darker in colors than picture, but I wasn’t disappointed. Very fun to watch as he moves around rock looking for food. Great addition!

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.

The Tailspot Blenny is an interesting species it's enjoyable to watch this fish. All my order was delivery in great shape and or still looking and doing great.

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.
