Segmented Sailfin Blenny
The Segmented Sailfin Blenny is also referred to as the Segmented Blenny. Its body is vertically striped, or segmented with alternating bands of yellow and reddish tan. This blenny shows tons of personality in the aquarium and is a great addition for the novice to experienced aquarist.
A well-established 30 gallon or larger aquarium with multiple swimming levels and plenty of rock is a suitable environment. The Segmented Blenny is not usually aggressive unless the tank mates appear to have a similar shape as it does. It is best to house singly unless kept in a larger tank and the two are a mated pair. It tends to perch and hop from rock to rock looking for microalgae to graze on.
The Segmented Blenny is a perfect candidate for the reef aquarium and is considered reef safe.

This blenny adds a lot of movement and color to my reef tank. It’s active and curious, always hopping between rocks. I’ve had it for six months and it’s still healthy and active. Great for beginners who want a lively, non-aggressive fish.
Tim Tucker –
The yellow and red stripes stand out well in the tank. It’s peaceful and doesn’t bother other fish. I keep it alone, and it’s very content perching on the rock surfaces.

I bought this for my new 40-gallon reef tank. It’s been thriving and has become a regular sight grazing on microalgae. The fish is active and doesn’t show aggression, even with other small fish.
