Reviewed by Guidarium Editorial DeskUpdated May 2, 2026
Not Recommended

Apistogramma Parrot and Blue Dolphin (Hap) are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Apistogramma Parrot and Blue Dolphin (Hap)?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Apistogramma Parrot is a moderately assertive species (6/10), while Blue Dolphin (Hap) is moderately assertive (5/10). This modest difference means Apistogramma Parrot may occasionally assert dominance over Blue Dolphin (Hap).

Apistogramma Parrot and Blue Dolphin (Hap) both frequent the Bottom (Substrate) and Middle (Open Water) 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 Apistogramma Parrot (5–7) and Blue Dolphin (Hap) (7.5–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Apistogramma Parrot needs 1–8 dGH while Blue Dolphin (Hap) requires 10–25 dGH.

Tank Setup

To house Apistogramma Parrot and Blue Dolphin (Hap) together, plan for an aquarium of at least 475 litres with a minimum length of 150 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

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

Why This Pairing Usually Fails in Practice

Apistogramma Parrot and Blue Dolphin (Hap) are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Apistogramma Parrot and Blue Dolphin (Hap).

Frequently Asked Questions

Can Apistogramma Parrot 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 Apistogramma Parrot and Blue Dolphin (Hap) need?

A minimum of 475 litres (tank length at least 150 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 Apistogramma Parrot 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 Apistogramma Parrot or Blue Dolphin (Hap) aggressive?

Apistogramma Parrot is moderately assertive (6/10) and Blue Dolphin (Hap) is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Apistogramma Parrot and Blue Dolphin (Hap) need?

Their pH requirements do not overlap. Apistogramma Parrot prefers 5–7, while Blue Dolphin (Hap) needs 7.5–8.6. This makes them incompatible in the same water chemistry.

How do I manage Apistogramma Parrot's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Apistogramma Parrot space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
