Can African Jewel Cichlid and Blue Tetra Live Together?
Keeping African Jewel Cichlid and Blue Tetra together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 110 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Can your tank handle African Jewel Cichlid and Blue Tetra?
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
African Jewel Cichlid is a semi-aggressive species (8/10), while Blue Tetra is moderately assertive (5/10). This modest difference means African Jewel Cichlid may occasionally assert dominance over Blue Tetra.
African Jewel Cichlid and Blue Tetra 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: Blue Tetra 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 Jewel Cichlid and Blue Tetra to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. 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 22°C and 26°C. Aim for the midpoint of this range (around 24.0°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 4–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house African Jewel Cichlid and Blue Tetra together, plan for an aquarium of at least 110 litres with a minimum length of 90 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Plants - Densely covered. Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: African Jewel Cichlid is a plant destroyer, which conflicts with Blue Tetra's requirement for live plants. Compromise where possible or prioritise the more critical need.
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 African Jewel Cichlid and Blue Tetra live together?
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 110 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do African Jewel Cichlid and Blue Tetra need?
A minimum of 110 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 African Jewel Cichlid and Blue Tetra together?
Keep the aquarium between 22°C and 26°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.
Are African Jewel Cichlid or Blue Tetra aggressive?
African Jewel Cichlid is semi-aggressive (8/10) and Blue Tetra is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do African Jewel Cichlid and Blue Tetra 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.
Will Blue Tetra nip African Jewel Cichlid's fins?
Blue Tetra is a known fin nipper. If African Jewel Cichlid has long or flowing fins, there is a real risk of fin damage. Keeping Blue Tetra in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage African Jewel Cichlid's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives African Jewel Cichlid 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.
