White-blotched River Stingray

Overview

White-blotched River Stingray (Potamotrygon leopoldi) is a bottom-dwelling fish for aquariums where the layout leaves enough open substrate area and the water stays stable.

Use these values as planning checks, then make sure the aquarium still has room for behavior, group needs, and calm community fish.

Care requirements

With a Intermediate – Advanced care level, White-blotched River Stingray is best for aquarists who can keep water quality steady and plan compatibility before adding the fish.

Because it uses the bottom area, leave enough open substrate area instead of crowding that part of the aquarium.

With a lifespan of up to 20 years, this is a fish to plan for long term rather than an impulse addition.

Aquarium size and space needs

An aquarium of 900 L or larger can be a reasonable starting point, but it should not be read as permission to overstock.

At up to 60 cm, White-blotched River Stingray stays small, but it still needs room to move, feed, and avoid constant competition.

Uses the bottom area, so leave enough open substrate area for movement and feeding.

Water parameters

The temperature range for this fish is 20 to 29 °C, which fits many tropical freshwater aquariums. Choose other fish with overlapping temperature needs.

The pH range for this fish is 6 to 7.5. That points to slightly acidic to neutral water, but stability is more important than sudden corrections.

The GH range for this fish is 0 to 5 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.

Temperament and compatibility

As a peaceful bottom-dwelling fish, White-blotched River Stingray is best kept with calm species that will not harass it or dominate the feeding area.

Because this fish uses the bottom area, compatibility is easier when other fish are not all competing for the same swimming space.

Swimming zone and behavior

This fish uses the bottom area, so leave enough open substrate area for movement and feeding.

Feeding

As an omnivore, White-blotched River Stingray should receive a varied diet rather than one repeated food type.

Because it feeds near the bottom, make sure food reaches the substrate and is not completely taken by faster fish in the open water.

Natural habitat and origin

This profile currently lists the origin as Brazil. Treat this as a broad regional note rather than a complete habitat description.

Before adding this fish

Use this checklist before treating the profile as a match for an existing aquarium.

• Plan for an aquarium of 900 L or larger.
• Make sure the bottom area has enough open substrate for a group.
• Choose other fish with overlapping temperature needs.
• Keep pH stable within the listed range instead of making sudden corrections.
• Avoid aggressive or highly competitive fish.
• Offer a varied diet suitable for an omnivorous bottom-dwelling fish.
