Can Congo Tetra and Ghost Shrimp Live Together?

🟡Possible with Caution

Keeping Congo Tetra and Ghost Shrimp together is possible but requires caution due to potential behavioral clashes. Provide a spacious tank of at least 132 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Behaviour & Temperament

Congo Tetra is a peaceful species (2/10), while Ghost Shrimp is peaceful (1/10). This modest difference means Congo Tetra may occasionally assert dominance over Ghost Shrimp.

In terms of spatial distribution, Congo Tetra prefers the Middle (Open Water) and Top (Surface) zones, whereas Ghost 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Congo Tetra is a known jumper, so a tight-fitting lid is essential.

To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

Water Parameters

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Congo Tetra and Ghost Shrimp together, plan for an aquarium of at least 132 litres with a minimum length of 90 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: Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater. 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 Congo Tetra and Ghost Shrimp live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 132 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Congo Tetra and Ghost Shrimp need?

A minimum of 132 litres (tank length at least 90 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 Congo Tetra and Ghost Shrimp together?

Keep the aquarium between 23°C and 28°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.

Are Congo Tetra or Ghost Shrimp aggressive?

Congo Tetra is peaceful (2/10) and Ghost Shrimp is peaceful (1/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Congo Tetra and Ghost Shrimp need?

Both species overlap in the 6.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
