Dragonets are often mis-categorized as gobies or blennies by fish sellers. Rock pools contain sea anemones, blennies, crabs and molluscs. Colorful species such as the ornate cowfish, blennies, and sea anemones can be found. In some species, such as redlip blennies, both polygyny and polyandry are observed. Redlip blennies largely feed on algae. These blennies have fang-like teeth with venom glands at their bases. Many blennies demonstrate mimicry of other species, such as Aspidontus taeniatus. Generally benthic fish, combtooth blennies spend much of their time on or near the bottom. Andamia is a genus of combtooth blennies found in the Pacific and Indian Oceans. Alticus is a genus of combtooth blennies found in the Pacific and Indian oceans. Meiacanthus is a genus of combtooth blennies found in the western Pacific and Indian oceans. Threefin or triplefin blennies are blenniiforms, small percomorph marine fish of the family Tripterygiidae. Some combtooth blennies form small groups, while others are solitary and territorial. Kirk's blennies inhabit waters near the shore, and often spend time out of the water. Combtooth blennies are active and often highly colourful, making them popular in the aquarium hobby.
