Common name: Maned blenny

General information

The Molly Miller Blenny, scientifically known as Scartella emarginata, is a small, characterful fish that is often overlooked in the reefkeeping hobby. Despite its modest size, this blenny is known for its voracious appetite for algae and its ability to help control microalgae growth in the aquarium. With a mottled brown and white appearance, it can blend into the rockwork and become a charming part of the clean-up crew.

Care

Molly Miller Blennies are hardy and adaptable, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for grazing and hiding. While they primarily feed on algae, they will also accept a variety of prepared foods. It's important to ensure that they have a steady supply of microalgae or supplemental feedings to keep them healthy.

Reproduction

In the wild, Molly Miller Blennies are protogynous hermaphrodites, meaning they start life as females and can change to males if necessary. In the aquarium, breeding is less common, but with a stable environment and a group of individuals, it's possible to observe their fascinating reproductive behavior.

Habitat

Native to the Western Atlantic, from North Carolina to Brazil, including the Gulf of Mexico and the Caribbean, Molly Miller Blennies are typically found in shallow waters. They inhabit rocky shorelines, coral reefs, and seagrass beds, where they can be seen grazing on algae and detritus.
