[edit] Sexing

Males have claspers, which are visible from young

[edit] Tank compatibility

A large animal that can take smaller fish that linger on the substrate. Best kept with peaceful but robust medium-sized to larger tankmates. Aggressive fish can damage a rays disc.

[edit] Diet

Carnivore. Almost anything that can fit into their mouths. A healthy specimen will not refuse food, especially live shrimps. Feed with meaty food such as shrimp and mussel.

[edit] Feeding regime

As often as possible as stingrays are high-metabolic fish that are constantly moving. The ideal way is to place excess live feeds (eg. feeder shrimps) in the tank to allow feeding at their own pace.

[edit] Environment Specifics

Comes from the amazon river, ideal pH would be around 6.5. Everyone likes a well lit aquarium right? Well not true, the stingrays do not. Stingrays spend most of the time on the riverbed where minimal light can penetrate through the murky waters of the amazon. Therefore it is not recommended that the aquarium be brightly lit for long periods of time as this might cause a great deal of stress to the rays.
Substrate is recommended in a stingray aquarium as rays hide in them when frightened or threathened. Substrate also provides traction when rays "walk" with their pelvic fins across aquariums. Adding substrate simulates a ray's natural habitat, the softer the better to allow for digging. However, this ultimately is personal preference. A ray will do just as well in an aquarium without substrate.

[edit] Behaviour

In the wild, the stingray spends most of its time at the bottom of the riverbed. In captivity they will again spend most of their time on the substrate, occasionally digging for food if possible, they will swim up the sides of the tank if food is on offer.

[edit] Identification

Typical Ray in shape with a round disc and long tail. The disc varies in colour but is generally a dark sandy brown in colour with many orange-brown spots which have thick darker borders. A marbled variant which is more striking with many brighter orange-yellow markings edged in dark brown is also available.
