Red Spot Blenny

Overview

The Red Spot Blenny is an attractive algae-grazing blenny with a mottled body covered in small reddish-orange spots, giving it more visual interest than many plainer blenny species. Like other combtooth blennies it spends its time picking algae off rock and glass rather than swimming in open water.

It does best in an established tank with a healthy film of algae for it to graze, and while it will take supplemental foods, it's happiest and most active in a system that already supports natural grazing.

It's a peaceful, engaging addition to a reef tank that adds both algae control and colour without any risk to corals or invertebrates.

Compatibility

Red Spot Blennies are peaceful and reef safe, ignoring corals, clams, and invertebrates. They can show mild territoriality toward other blennies of similar shape, particularly in smaller tanks, but generally coexist well with the wider community.

Health & quarantine

This species needs an established tank with adequate algae growth to avoid slow starvation over time — a thinning body is the main warning sign to monitor. Quarantine for two to four weeks is recommended good practice, and as with all blennies, avoid copper-based treatments due to their lack of scales.
