Common name: Triplefin blennies

Tripterygion is a genus of small, colorful fish known as triplefin blennies, found primarily in the Eastern Atlantic and the Mediterranean Sea. These fish are characterized by their three dorsal fins and vibrant coloration, which can range from bright reds to yellows. They are popular in the reefkeeping hobby for their hardiness and ability to adapt to life in an aquarium. Triplefin blennies are generally peaceful and can be kept with a variety of other species, making them a good choice for community tanks. They are known to feed on small invertebrates and algae, helping to control algae growth in the tank.
