Description
The Spottail Dartfish is a slender, peaceful saltwater fish characterized by its pale, often iridescent body and a prominent black spot on its forked caudal fin. They are planktivores that hover in the water column, quickly retreating into sandy burrows or rock crevices when startled. This species makes an excellent addition to a peaceful reef aquarium.
