Origin

Sexing

Tank compatibility

Like other Rays, this fish is best kept in extra large species tanks. They are predators and will eat what they can fit in their mouths. They can be kept, with caution, with peaceful and large yet robust mid-top dwelling fish which won't fin nip the Ray's delicate disc.
