Can Banded Chromide and Rummy-Nose Tetra Live Together?
Banded Chromide and Rummy-Nose Tetra are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle Banded Chromide and Rummy-Nose 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
Banded Chromide is a moderately assertive species (5/10), while Rummy-Nose Tetra is peaceful (1/10). This notable difference means Banded Chromide may occasionally assert dominance over Rummy-Nose Tetra.
Banded Chromide and Rummy-Nose Tetra both frequent the Middle (Open Water) and Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.
Water Parameters
The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
The pH requirements of Banded Chromide (7.5–8.5) and Rummy-Nose Tetra (5.5–7) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Banded Chromide and Rummy-Nose Tetra together, plan for an aquarium of at least 450 litres with a minimum length of 150 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Plants - lighly covered, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Banded Chromide is a plant destroyer, which conflicts with Rummy-Nose 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.
Suitable Tank Sizes
Standard aquarium sizes large enough for both Banded Chromide and Rummy-Nose Tetra.
Diet & Feeding
Feeding time deserves special attention with this pairing. Banded Chromide is a known shrimp eater and may prey on small invertebrates or nano fish like Rummy-Nose Tetra.

Frequently Asked Questions
Can Banded Chromide and Rummy-Nose Tetra live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Banded Chromide and Rummy-Nose Tetra need?
A minimum of 450 litres (tank length at least 150 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 Banded Chromide and Rummy-Nose Tetra together?
Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.
Are Banded Chromide or Rummy-Nose Tetra aggressive?
Banded Chromide is moderately assertive (5/10) and Rummy-Nose Tetra is peaceful (1/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Banded Chromide and Rummy-Nose Tetra need?
Their pH requirements do not overlap. Banded Chromide prefers 7.5–8.5, while Rummy-Nose Tetra needs 5.5–7. This makes them incompatible in the same water chemistry.
How do I manage Banded Chromide's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Banded Chromide 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.
