The Molly Miller Blenny (Scartella cristata) is a combtooth blenny found among rocky reefs in the Caribbean. It spends its time scavenging for small crustaceans or algae. While typically peaceful, they can be aggressive to fish with a similar body shape, so it is recommended to keep one per tank. It should be fed vitamin-enriched crustaceans, with occasional algae or seaweed mixed in.
