Common name: Triplefin blennies

The Tripterygiidae family, commonly known as triplefin blennies or threefin blennies, comprises small, colorful fish often found in shallow reefs. They are named for their distinctive three dorsal fins. These fish are known for their hardiness and ability to adapt to various microhabitats within the reef. Triplefins are benthic and often seen perching on coral or rock surfaces, feeding on small invertebrates. Their small size and peaceful nature make them suitable for most reef aquariums, where they add diversity and activity. They are also useful in controlling microalgae growth.
