Care
The Red-spot Flymo blenny is known from clear, shallow, coastal and intertidal reef flats, and current-swept seaward reefs, usually where algal growth is prolific. Here, they feed on algae and small invertebrates and spend a good portion of their time in small crevices with just their heads protruding, keeping a watchful eye on their surroundings. The Red-spot Flymo is often regarded as a utility fish for helping to control various algal growths in the aquarium. However, these are very personable fish and are fascinating to observe, regardless of their excellent ability at removing and consuming algae. The tank must be well established, and of a good size; these combtooth blennies have been known to starve in smaller quarters once the main food source has been depleted and not had time to re-establish. When Red-spot Flymo blennies feed, skip over rocks, graze décor and generally go about their business, they tend to stir up detritus where it goes into suspension and is then removed by the filtration. Ensure that the tank has efficient filtration with areas of brisk water movement (in order to simulate the surge-like conditions this fish favours) along with some calmer resting spots out of the current. As this species requires a mature tank, it works out well that this should be the last fish added to the tank, preferably at a size around 2.5" where it should not be over-dominant. However, in general, Red-spot Flymo blennies can be fairly feisty and quite territorial over the bottom of the aquarium, particularly as they mature; therefore it is best to keep only one per tank, and careful consideration given to tankmates - avoiding other blennies and similar-looking bottom dwelling species such as gobies (unless you are blessed with a tank of vast proportions incorporating a huge number of visual barriers amongst the rockwork, and more than enough food to go round on a continual basis). It should be noted that the Red-spot Flymo will not feed on every kind of algae - they particularly relish the filamentous type, but will ignore bubble and slime algae. Ensure corals are firmly attached, as large blennies may disturb them with their feeding habits and when hopping about looking for a suitable perch from which they can survey their domain. May also be seen on sale as the Red Spotted Blenny.
Feeding
By far and away, this species does best if a decent growth of filamentous algae is present in the aquarium for the fish to harvest at its leisure. Also offer plenty of vegetable matter, including frozen foods that contain marine algae and Spirulina. Nori (dried seaweed), algae flake and algae wafers formulated for marine fish are usually met with much enthusiasm. If you have space in a well lit sump, filamentous algae can be cultured on pieces of rock, and occasionally rotated with some of the pieces in the main display aquarium.
Breeding
This species has not been bred in the home aquarium. In the wild these fish form distinct pairs. The eggs, which are demersal and adhesive, are laid in a crevice which is then guarded.
