Behaviour & Temperament
Apistogramma baenschi (Inca 50) is a moderately assertive species (5/10), while Vampire Shrimp is peaceful (0/10). This notable difference means Apistogramma baenschi (Inca 50) may occasionally assert dominance over Vampire Shrimp.
Apistogramma baenschi (Inca 50) and Vampire Shrimp 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.
Worth noting: Vampire Shrimp is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
Water Parameters
The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.
Both fish can tolerate a pH between 6.5 and 6.5. Maintaining a stable value within this band is more important than hitting an exact number.
Hardness requirements are incompatible: Apistogramma baenschi (Inca 50) needs 1–5 dGH while Vampire Shrimp requires 6–15 dGH.

Tank Setup
To house Apistogramma baenschi (Inca 50) and Vampire Shrimp together, plan for an aquarium of at least 75 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.
Apistogramma baenschi (Inca 50) prefers Low (Still Water) flow while Vampire Shrimp needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Frequently Asked Questions
Can Apistogramma baenschi (Inca 50) and Vampire Shrimp live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Apistogramma baenschi (Inca 50) and Vampire Shrimp need?
A minimum of 75 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 Apistogramma baenschi (Inca 50) and Vampire Shrimp together?
Keep the aquarium between 24°C and 26°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.
Are Apistogramma baenschi (Inca 50) or Vampire Shrimp aggressive?
Apistogramma baenschi (Inca 50) is moderately assertive (5/10) and Vampire Shrimp is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Apistogramma baenschi (Inca 50) and Vampire Shrimp need?
Both species overlap in the 6.5–6.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Apistogramma baenschi (Inca 50)'s territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Apistogramma baenschi (Inca 50) 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.
Does Vampire Shrimp being nocturnal affect compatibility?
Vampire Shrimp is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Vampire Shrimp during evening hours.
