Can Finger Fish and Florida Gar Live Together?

Possible with Caution

Keeping Finger Fish and Florida Gar together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 1100 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Finger Fish and Florida Gar?

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

Finger Fish 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 Finger Fish.

Finger Fish and Florida Gar 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: 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: Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.

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 7.5 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 12–20 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Finger Fish 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: Smooth Gravel (Sensitive Barbels), 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.

Frequently Asked Questions

Can Finger Fish and Florida Gar live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 1100 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Finger Fish and Florida Gar need?

A minimum of 1100 litres (tank length at least 240 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 Finger Fish and Florida Gar 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 Finger Fish or Florida Gar aggressive?

Finger Fish is moderately assertive (5/10) and Florida Gar is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Finger Fish and Florida Gar need?

Both species overlap in the 7.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Finger Fish nip Florida Gar's fins?

Finger Fish is a known fin nipper. If Florida Gar has long or flowing fins, there is a real risk of fin damage. Keeping Finger Fish in a larger group can help redirect nipping behaviour toward conspecifics.
