Can Blue Dolphin (Hap) and Hongsloi Apistogramma Live Together?
Blue Dolphin (Hap) and Hongsloi Apistogramma 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.
At a Glance
Can your tank handle Blue Dolphin (Hap) and Hongsloi Apistogramma?
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
Both Blue Dolphin (Hap) and Hongsloi Apistogramma 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.
Blue Dolphin (Hap) and Hongsloi Apistogramma both frequent the Middle (Open Water) and 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.
Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.
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 Blue Dolphin (Hap) (7.5–8.6) and Hongsloi Apistogramma (5.5–7) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Blue Dolphin (Hap) needs 10–25 dGH while Hongsloi Apistogramma requires 1–8 dGH.

Tank Setup
To house Blue Dolphin (Hap) and Hongsloi Apistogramma 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), Smooth Gravel (Sensitive Barbels), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered. 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.
Suitable Tank Sizes
Standard aquarium sizes large enough for both Blue Dolphin (Hap) and Hongsloi Apistogramma.

Frequently Asked Questions
Can Blue Dolphin (Hap) and Hongsloi Apistogramma live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Blue Dolphin (Hap) and Hongsloi Apistogramma 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 Blue Dolphin (Hap) and Hongsloi Apistogramma 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 Blue Dolphin (Hap) or Hongsloi Apistogramma aggressive?
Blue Dolphin (Hap) is moderately assertive (5/10) and Hongsloi Apistogramma is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Blue Dolphin (Hap) and Hongsloi Apistogramma need?
Their pH requirements do not overlap. Blue Dolphin (Hap) prefers 7.5–8.6, while Hongsloi Apistogramma needs 5.5–7. This makes them incompatible in the same water chemistry.
How do I manage Hongsloi Apistogramma's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Hongsloi Apistogramma 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.
