Can Agassiz's Dwarf Cichlid and Humpbacked Limia Live Together?
Agassiz's Dwarf Cichlid and Humpbacked Limia 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 Agassiz's Dwarf Cichlid and Humpbacked Limia?
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
Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while Humpbacked Limia is peaceful (2/10). This modest difference means Agassiz's Dwarf Cichlid may occasionally assert dominance over Humpbacked Limia.
In terms of spatial distribution, Agassiz's Dwarf Cichlid prefers the Bottom (Substrate) zone, whereas Humpbacked Limia occupies the Middle (Open Water) and Top (Surface) 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.
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 Agassiz's Dwarf Cichlid (4.5–7) and Humpbacked Limia (7.2–8.5) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Agassiz's Dwarf Cichlid needs 1–8 dGH while Humpbacked Limia requires 10–25 dGH.

Tank Setup
To house Agassiz's Dwarf Cichlid and Humpbacked Limia 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), Plants - Densely covered, Established Algae (Otocinclus). 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.

Frequently Asked Questions
Can Agassiz's Dwarf Cichlid and Humpbacked Limia 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 Humpbacked Limia 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 Agassiz's Dwarf Cichlid and Humpbacked Limia 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 Humpbacked Limia aggressive?
Agassiz's Dwarf Cichlid is moderately assertive (5/10) and Humpbacked Limia is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Agassiz's Dwarf Cichlid and Humpbacked Limia need?
Their pH requirements do not overlap. Agassiz's Dwarf Cichlid prefers 4.5–7, while Humpbacked Limia needs 7.2–8.5. This makes them incompatible in the same water chemistry.
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.
