Can Agassiz's Dwarf Cichlid and Endler's Livebearer Live Together?

🔴Not Recommended

Agassiz's Dwarf Cichlid and Endler's Livebearer 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.

Behaviour & Temperament

Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while Endler's Livebearer is peaceful (1/10). This notable difference means Agassiz's Dwarf Cichlid may occasionally assert dominance over Endler's Livebearer.

In terms of spatial distribution, Agassiz's Dwarf Cichlid 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.

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: Agassiz's Dwarf Cichlid needs 1–8 dGH while Endler's Livebearer requires 10–25 dGH. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Agassiz's Dwarf Cichlid and Endler's Livebearer together, plan for an aquarium of at least 72 litres with a minimum length of 60 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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.

Diet & Feeding

Feeding time deserves special attention with this pairing. Agassiz's Dwarf Cichlid is a known shrimp eater and may prey on small invertebrates or nano fish like Endler's Livebearer.

Frequently Asked Questions

Can Agassiz's Dwarf Cichlid 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 Agassiz's Dwarf Cichlid and Endler's Livebearer need?

A minimum of 72 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 Agassiz's Dwarf Cichlid 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 Agassiz's Dwarf Cichlid or Endler's Livebearer aggressive?

Agassiz's Dwarf Cichlid 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 Agassiz's Dwarf Cichlid and Endler's Livebearer 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 Agassiz's Dwarf Cichlid's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Agassiz's Dwarf Cichlid 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.
