Can Apistogramma uaupesi and Florida Gar Live Together?

Apistogramma uaupesi is a moderately assertive species (5/10), while Florida Gar is semi-aggressive (7/10). This modest difference means Florida Gar may occasionally assert dominance over Apistogramma uaupesi.

In terms of spatial distribution, Apistogramma uaupesi prefers the Bottom (Substrate) zone, whereas Florida Gar 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.

Worth noting: Florida Gar is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 29°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 6. Maintaining a stable value within this band is more important than hitting an exact number.

Hardness requirements are incompatible: Apistogramma uaupesi needs 0–5 dGH while Florida Gar requires 8–20 dGH.

To house Apistogramma uaupesi and Florida Gar together, plan for an aquarium of at least 1100 litres with a minimum length of 240 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.
