 How to set up a tank for rays

Fejer Potamotrygon Rays (the river stingrays) are among the most extraordinary fish available for freshwater aquarists. Ordinary rays could be challenging to keep, although these species are often kept with considerably greater success than other rays.

Fejer

Fejer Filtration and tank size are the most important factors of a ray tank set-up. Use an efficient filter (biological). The temperature should be maintained between 20 – 29 degrees C., or  68 – 88 F. A tank size capacity of 1000 litres or 265 gallons is recommended as a minimum size. Creating ideal aquarium water chemistry will help your stingray to thrive. A water chemistry of pH 6.0 – 7.5 is advised. Dimmed lighting is sufficient to keep rays, create a natural looking environment (using river sand).

Compatible tank mates for stingrays

Rays are predators, but prefer a quiet and peaceful life, they will thrive when aggressive and territorial companions do not surround them. Stingrays are quiet fish and prefer to avoid conflict. Many medium sized to larger non- aggressive fish are compatible. Arawana´s , Gongo Tetras, Silver dollars, Peacock bass and Oscars are among many good companions for stingrays.

Black diamond feeding

Wild rays normally feed on other fish and invertebrates such as crustaceans and worms. Also small fish and shrimp are good meals. They are known for their big appetite and will need feeding at least twice a day. An exclusively meat diet is preferred for these rays to thrive.
