Behaviour & Temperament
Arrowhead Puffer is a highly aggressive species (10/10), while Florida Gar is semi-aggressive (7/10). This modest difference means Arrowhead Puffer may occasionally assert dominance over Florida Gar.
Both Arrowhead Puffer and Florida Gar are highly aggressive, increasing the risk of violent confrontations.
In terms of spatial distribution, Arrowhead Puffer 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.
To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.
Water Parameters
The safe temperature window for both species falls between 22°C and 28°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 7.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 8–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Arrowhead Puffer 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.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Sand (Sifters), Plants - Floating. Meeting these requirements will help both species thrive.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
