Can Apistogramma Mamoré and Turquoise Rainbowfish Live Together?
Apistogramma Mamoré and Turquoise Rainbowfish are not recommended as tank mates due to 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 Apistogramma Mamoré and Turquoise Rainbowfish?
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 Mamoré is a generally mild-mannered species (4/10), while Turquoise Rainbowfish is peaceful (2/10). This modest difference means Apistogramma Mamoré may occasionally assert dominance over Turquoise Rainbowfish.
Apistogramma Mamoré and Turquoise Rainbowfish both frequent the 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.
Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.
Worth noting: Turquoise Rainbowfish 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 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.
Both fish can tolerate a pH between 7 and 7. Maintaining a stable value within this band is more important than hitting an exact number.
Hardness requirements are incompatible: Apistogramma Mamoré needs 1–8 dGH while Turquoise Rainbowfish requires 10–25 dGH.

Tank Setup
To house Apistogramma Mamoré and Turquoise Rainbowfish together, plan for an aquarium of at least 160 litres with a minimum length of 120 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, Plants - lighly covered. 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.
Suitable Tank Sizes
Standard aquarium sizes large enough for both Apistogramma Mamoré and Turquoise Rainbowfish.
55 Gallon Standard
60 Gallon Breeder
75 Gallon Standard

Diet & Feeding
Feeding time deserves special attention with this pairing. Turquoise Rainbowfish is an aggressive eater that may prevent Apistogramma Mamoré from getting enough food.
Because Turquoise Rainbowfish is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Apistogramma Mamoré receives an adequate share.

Frequently Asked Questions
Can Apistogramma Mamoré and Turquoise Rainbowfish live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Apistogramma Mamoré and Turquoise Rainbowfish need?
A minimum of 160 litres (tank length at least 120 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 Mamoré and Turquoise Rainbowfish together?
Keep the aquarium between 24°C and 25°C. A target of around 24.5°C sits comfortably within both species' preferred ranges.
Are Apistogramma Mamoré or Turquoise Rainbowfish aggressive?
Apistogramma Mamoré is generally mild-mannered (4/10) and Turquoise Rainbowfish is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Apistogramma Mamoré and Turquoise Rainbowfish need?
Both species overlap in the 7–7 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Apistogramma Mamoré's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Apistogramma Mamoré 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.
