Linear Blenny by Live Aquaria
The Linear Blenny, also known as the Lined Blenny, has a distinctive coloration with a white lower half and a brown to black upper half. It is a small blenny species known for its large eyes and small mouth, giving it a comical appearance.
These fish are well-suited for both reef and peaceful fish-only aquariums, regardless of tank size. They naturally inhabit crevices and rocky areas on the ocean floor and require a minimum tank volume of 30 gallons with ample live rock for grazing, perching, and hiding.
While considered reef-safe, Linear Blennies may nip at the polyps or bases of Acropora species and other SPS corals. They should not be kept with aggressive fish that might intimidate them.

Added a Linear Blenny to my 40-gallon reef tank and it’s been thriving. It spends most of its time in the rock crevices, looks active, and doesn’t bother my corals. Very easy to care for and adds a unique, comical touch to the tank.
Melanie Kelly –
The fish is small but very interesting. It’s not aggressive and seems to enjoy the rock structure. I noticed it occasionally nips at a weak Acropora, so I’ve moved it farther away. Still, a great addition to a peaceful reef setup.

Perfect for a beginner reef keeper. The blenny is calm, active, and blends well with the environment. It doesn’t stress the tank or other fish and has become a regular sight in the corner of my tank.
