🐠 Segmented Sailfin Blenny (Salarias segmentatus)
A Body Divided Into Vertical Yellow and Reddish-Tan Segments • A Smaller, More Colourful Relative of the Lawnmower Blenny • A Characterful, Inquisitive Species
 
📋 The Segmented Sailfin Blenny, also known simply as the Segmented Blenny, has an eye-catching, distinctive appearance, a body divided into vertical segments alternating between yellow and reddish-tan, with red spots along the dorsal fin and flanks, plus bushy cirri between the eyes. It's a smaller, more colourful relative of the popular Lawnmower Blenny.
It comes from shallow, algae-rich lagoons and reef flats across the Western Central Pacific, spending its days perching on rock, hopping between vantage points, and grazing on filamentous algae, diatoms, and detritus. Every Segmented Sailfin Blenny we ship is feeding well.
This is a characterful, inquisitive fish, often seen perched watching its surroundings. It's fully reef safe and generally peaceful, though territorial toward other blennies or similarly shaped fish, best kept singly unless housing a confirmed mated pair in a larger tank. As with all Salarias blennies, this species needs an established tank with real ongoing algae growth to thrive long-term. It reaches up to 11cm, so a 115L tank suits it well.
