Can Apistogramma elizabethae and Endler's Livebearer Live Together?
Apistogramma elizabethae and Endler's Livebearer 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 Apistogramma elizabethae and Endler's Livebearer?
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 elizabethae is a moderately assertive species (5/10), while Endler's Livebearer is peaceful (1/10). This notable difference means Apistogramma elizabethae may occasionally assert dominance over Endler's Livebearer.
In terms of spatial distribution, Apistogramma elizabethae prefers the Bottom (Substrate) zone, whereas Endler's Livebearer occupies the Top (Surface) and Middle (Open Water) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.
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: Endler's Livebearer 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 Apistogramma elizabethae (4–6.5) and Endler's Livebearer (7–8.5) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Apistogramma elizabethae needs 0–5 dGH while Endler's Livebearer requires 10–25 dGH.
Tank Setup
To house Apistogramma elizabethae and Endler's Livebearer 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered, Plants - Floating. 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 elizabethae and Endler's Livebearer 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.

Diet & Feeding
Feeding time deserves special attention with this pairing. Apistogramma elizabethae is a known shrimp eater and may prey on small invertebrates or nano fish like Endler's Livebearer.
Frequently Asked Questions
Can Apistogramma elizabethae and Endler's Livebearer live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Apistogramma elizabethae and Endler's Livebearer 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 Apistogramma elizabethae and Endler's Livebearer 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 elizabethae or Endler's Livebearer aggressive?
Apistogramma elizabethae is moderately assertive (5/10) and Endler's Livebearer is peaceful (1/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Apistogramma elizabethae and Endler's Livebearer need?
Their pH requirements do not overlap. Apistogramma elizabethae prefers 4–6.5, while Endler's Livebearer needs 7–8.5. This makes them incompatible in the same water chemistry.
How do I manage Apistogramma elizabethae's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Apistogramma elizabethae 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.
