Can Cherry Shrimp and Florida Gar Live Together?
Cherry Shrimp and Florida Gar are not recommended as tank mates due to piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Behaviour & Temperament
Cherry Shrimp is a peaceful species (0/10), while Florida Gar is semi-aggressive (7/10). This notable difference means Florida Gar may occasionally assert dominance over Cherry Shrimp.
Large aggression gap (7 points) between Cherry Shrimp and Florida Gar increases stress risk for the more peaceful fish.
Cherry Shrimp 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.
There is a critical concern: the Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..
Worth noting: Florida Gar is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 18°C and 28°C. Aim for the midpoint of this range (around 23.0°C) for optimal comfort.
Both fish can tolerate a pH between 6.5 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 8–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Cherry Shrimp 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.
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: Established Algae (Otocinclus), Plants - Densely covered, Leaf Litter/Blackwater, 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 Cherry Shrimp and Florida Gar live together?▾
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Cherry Shrimp 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 Cherry Shrimp and Florida Gar together?▾
Keep the aquarium between 18°C and 28°C. A target of around 23.0°C sits comfortably within both species' preferred ranges.
Are Cherry Shrimp or Florida Gar aggressive?▾
Cherry Shrimp is peaceful (0/10) and Florida Gar is semi-aggressive (7/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Cherry Shrimp and Florida Gar need?▾
Both species overlap in the 6.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
