Description
It has a classic disk-shaped body shape for stingrays.
Habitat
Originally from South America.
Behavior and compatibility
They are the top predators in their ecosystem, and for this reason they pose a direct threat to most small fish and freshwater shrimp.
Care and maintenance
If you manage to find a healthy stingray, then for one individual you will need an aquarium with a size of 600 liters, and the bottom area in this case will be more important than the height of the tank.
Diet
The diet is based on small fish, freshwater shrimp and large invertebrates such as worms.
Breeding and reproduction
The reticulated stingray is a viviparous fish species in which the fry develop in the mother's body and are born fully formed.
Buying guide
These fish can often be found on sale.
Frequently asked questions
The essentials: size, tank volume, water parameters and care
How big does Net stingray get?
An adult reaches 35 cm in length. Plan the tank around the maximum size: the fish quickly outgrows a cramped setup.
What size aquarium does Net stingray need?
The minimum recommended volume is 600 L. A smaller tank speeds up nitrate build-up and raises stress levels.
What water parameters does Net stingray need?
Temperature 24–26 °C, pH 6.5–7.5, hardness 4–10 dGH. Stability matters more than exact values: sudden swings are harder on the fish than a small deviation from the ideal.
How long does Net stingray live?
Around 10 years when kept properly. Lifespan depends directly on tank volume, water quality and a varied diet.
Is Net stingray aggressive?
Temperament: peaceful (regular). This is a predatory species — any fish small enough to fit in its mouth will eventually be eaten.
How many Net stingray should be kept together?
Recommended setup: both solitary and in group (flexible). Ignoring this is a common cause of stress and disease.
What does Net stingray eat?
Diet type: meat / protein (live, frozen, fresh). Feed small portions that are finished within a couple of minutes — overfeeding does more harm than underfeeding.
What is the scientific name of Net stingray?
The scientific name of the species is Potamotrygon orbignyi, family Potamotrygonidae (River stingrays). It also appears in the literature as: Potamotrygon dorbignyi, Potamotrygon dumerilii, Potamotrygon reticulatus.
