Description
The Threadfin Dartfish is a striking saltwater fish known for its elongated body, vibrant blue and purple coloration, and a distinctive long, flowing dorsal fin ray. It is a peaceful planktivore that hovers gracefully in the water column, darting into rockwork or sand when startled. This species adds elegance and calm movement to a reef or fish-only aquarium.
