Can African Lungfish and Florida Gar Live Together?

🟡Possible with Caution

Keeping African Lungfish and Florida Gar together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 1320 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Behaviour & Temperament

African Lungfish is a highly aggressive species (10/10), while Florida Gar is semi-aggressive (7/10). This modest difference means African Lungfish may occasionally assert dominance over Florida Gar.

Both African Lungfish and Florida Gar are highly aggressive, increasing the risk of violent confrontations.

African Lungfish and Florida Gar both frequent the Middle (Open Water) and Top (Surface) 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: African Lungfish 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 African Lungfish and Florida Gar 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 24°C and 30°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 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 8–20 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house African Lungfish and Florida Gar together, plan for an aquarium of at least 1320 litres with a minimum length of 240 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), 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.

Frequently Asked Questions

Can African Lungfish and Florida Gar live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 1320 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do African Lungfish and Florida Gar need?

A minimum of 1320 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 African Lungfish and Florida Gar together?

Keep the aquarium between 24°C and 30°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.

Are African Lungfish or Florida Gar aggressive?

African Lungfish is highly aggressive (10/10) and Florida Gar is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do African Lungfish and Florida Gar need?

Both species overlap in the 6–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage African Lungfish's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives African Lungfish 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.
