Algae Blenny by Real Aquatics
A mottled brown blenny with a blunt comical face and constantly moving eyes, sold as a working algae grazer. Full of character, and dependent on there being algae to eat.
Feeding
Grazes filamentous algae from rock and glass. Once the tank is clean it must be fed – dried algae sheets, spirulina pellets and vegetable-based frozen foods.
Compatibility
Reef safe and peaceful toward other species, though territorial with other blennies. Keep one per tank unless it is large.
Behaviour and Personality
Perches on rock and glass, propped on its pectoral fins, then hops between vantage points. Constantly scanning with independently moving eyes.
Important Note
This is the important part: it is bought to clear algae, clears it, and then slowly starves.

Will the Algae Blenny get aggressive with other fish?
It is territorial with other blennies and may become aggressive in the presence of similar species. Keep one per tank or ensure the tank is large enough.

The blenny is very active and adds a lot of character to the tank. It clears algae effectively at first, but after a few weeks it stops eating and becomes inactive. I now feed it regularly to keep it healthy.

Great for algae control, especially on glass and rocks. It’s entertaining to watch with its moving eyes and hopping behavior. After a few weeks, I had to start feeding it to prevent it from starving.
Caroline Anderson –
It works well in the beginning, but once the tank is clean, it stops eating. I’ve had to supplement its diet with spirulina and frozen vegetables to keep it alive.

A unique and lively addition to my reef tank. The way it perches and scans is fascinating. I feed it daily now to maintain its health after the algae phase ends.

Good for algae removal, but not a long-term solution. It needs consistent feeding after the tank is clean. Works best in a tank with minimal algae growth.
