Behaviour & Temperament
Flower Stingray is a moderately assertive species (6/10), while Peter's Elephantnose Fish is generally mild-mannered (4/10). This modest difference means Flower Stingray may occasionally assert dominance over Peter's Elephantnose Fish.
Flower Stingray and Peter's Elephantnose Fish both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
Worth noting: Peter's Elephantnose Fish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Peter's Elephantnose Fish is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
Both fish can tolerate a pH between 6 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 2–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Flower Stingray and Peter's Elephantnose Fish together, plan for an aquarium of at least 1700 litres with a minimum length of 240 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Plants - lighly covered, Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Flower Stingray is a plant destroyer, which conflicts with Peter's Elephantnose Fish's requirement for live plants. Compromise where possible or prioritise the more critical need.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
