Behaviour & Temperament

Both Antennae Stingray and Blue Dolphin (Hap) are moderately assertive species with an aggression score of 5/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Antennae Stingray and Blue Dolphin (Hap) 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.

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.

The pH requirements of Antennae Stingray (6–7) and Blue Dolphin (Hap) (7.5–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Antennae Stingray and Blue Dolphin (Hap) together, plan for an aquarium of at least 2500 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.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions

Can Antennae Stingray and Blue Dolphin (Hap) live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Antennae Stingray and Blue Dolphin (Hap) need?

A minimum of 2500 litres (tank length at least 240 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Antennae Stingray and Blue Dolphin (Hap) together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Antennae Stingray or Blue Dolphin (Hap) aggressive?

Antennae Stingray is moderately assertive (5/10) and Blue Dolphin (Hap) is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Antennae Stingray and Blue Dolphin (Hap) need?

Their pH requirements do not overlap. Antennae Stingray prefers 6–7, while Blue Dolphin (Hap) needs 7.5–8.6. This makes them incompatible in the same water chemistry.
