Behaviour & Temperament

Cuban Gar is a moderately assertive species (6/10), while Silver Tiger Perch (American Tigerfish) is semi-aggressive (7/10). This modest difference means Silver Tiger Perch (American Tigerfish) may occasionally assert dominance over Cuban Gar.

Cuban Gar and Silver Tiger Perch (American Tigerfish) both frequent the Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

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

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Cuban Gar and Silver Tiger Perch (American Tigerfish) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.

Water Parameters

The safe temperature window for both species falls between 22Β°C and 28Β°C. Aim for the midpoint of this range (around 25.0Β°C) for optimal comfort.

Both fish can tolerate a pH between 7.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 15–20 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Cuban Gar and Silver Tiger Perch (American Tigerfish) together, plan for an aquarium of at least 3785 litres with a minimum length of 300 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 β€” caves, driftwood, and dense plant clusters β€” so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). 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.
