Common name: Dartfish

Ptereleotris is a genus of small, colorful fish commonly known as dartfish, firefish, or scissortail gobies. These peaceful and shy species are popular in the reef aquarium hobby for their vibrant colors and interesting behaviors. They are known for their elongated bodies and tendency to hover in the water column, darting back to their burrows when startled. Ptereleotris species are generally hardy and can be kept in aquariums with other peaceful fish and invertebrates, making them suitable for community tanks. They require a well-established tank with plenty of hiding places and a sandy substrate to mimic their natural habitat.
