Can Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Forktail Blue-eye Live Together?
Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Forktail Blue-eye are not recommended as tank mates due to conflicting pH requirements. 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 Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Forktail Blue-eye?

Behaviour & Temperament
Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) is a generally mild-mannered species (4/10), while Forktail Blue-eye is peaceful (2/10). This modest difference means Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) may occasionally assert dominance over Forktail Blue-eye.
Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Forktail Blue-eye 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. Shrimp eaters may also prey on very small nano fish.
Worth noting: Forktail Blue-eye 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.
The pH requirements of Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) (4.5–6.5) and Forktail Blue-eye (7–8) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 5–5 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Forktail Blue-eye together, plan for an aquarium of at least 55 litres with a minimum length of 60 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), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, 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.

Frequently Asked Questions
Can Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Forktail Blue-eye live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Forktail Blue-eye need?
A minimum of 55 litres (tank length at least 60 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 Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Forktail Blue-eye 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 Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) or Forktail Blue-eye aggressive?
Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) is generally mild-mannered (4/10) and Forktail Blue-eye is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Forktail Blue-eye need?
Their pH requirements do not overlap. Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) prefers 4.5–6.5, while Forktail Blue-eye needs 7–8. This makes them incompatible in the same water chemistry.
How do I manage Barlow's Dwarf Cichlid (Apistogramma Maulbrüter)'s territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) 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.
