saltwater stingrays?

[krj-1168]

Among the blue spotted stingrays - stick with the D. kuhlii. hardier species - easier to keep.

Other good SW rays - among the round rays - the Cortez, the Yellow Stingray, & Bulls-eye. Also The Atlantic Stingray is a good choice.

As to size, some SW rays are quite small but other get over 6' across the wings.

True - but the species I suggested about all have max. disc widths of 10-24" - which tends to make them better suited for home aquaria or at least ray ponds of under 2,000 gallons.
