Black-tailed antenna ray

Round snout, tiny spiracles and a long dark whip; dwarf is not a tank-size guarantee.

Adults have a near-circular disc and short rounded snout, with fine pale curves forming small rosettes or irregular ocelli. The distal whip is usually dark purplish-brown, though pale-tailed individuals occur.

Adult size

Up to 24.7 cm (disc width)

Native range

Originally recorded from the Pachitea River, a tributary of the Ucayali, upstream of Puerto Inca in Peru.

Natural habitat

Unknown

The dwarf name reflects early small specimens; females reach 52.3cm DW, so it is not a small-tank fish.
