Can Florida Gar and Red Goldflake Shrimp Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Florida Gar and Red Goldflake Shrimp 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.

Can your tank handle Florida Gar and Red Goldflake Shrimp?

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

Florida Gar is a semi-aggressive species (7/10), while Red Goldflake Shrimp is peaceful (0/10). This notable difference means Florida Gar may occasionally assert dominance over Red Goldflake Shrimp.

Large aggression gap (7 points) between Florida Gar and Red Goldflake Shrimp increases stress risk for the more peaceful fish.

In terms of spatial distribution, Florida Gar prefers the Top (Surface) and Middle (Open Water) zones, whereas Red Goldflake Shrimp occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..

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.

Water Parameters

The safe temperature window for both species falls between 26°C and 29°C. Aim for the midpoint of this range (around 27.5°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 8–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Florida Gar and Red Goldflake Shrimp 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.

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: Plants - Floating, Sand (Sifters), Established Algae (Otocinclus). 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.

Why This Pairing Usually Fails in Practice

Florida Gar and Red Goldflake Shrimp are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Frequently Asked Questions

Can Florida Gar and Red Goldflake Shrimp live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Florida Gar and Red Goldflake Shrimp 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 Florida Gar and Red Goldflake Shrimp together?

Keep the aquarium between 26°C and 29°C. A target of around 27.5°C sits comfortably within both species' preferred ranges.

Are Florida Gar or Red Goldflake Shrimp aggressive?

Florida Gar is semi-aggressive (7/10) and Red Goldflake Shrimp is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Florida Gar and Red Goldflake Shrimp 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.
