Can your tank handle Bahia Red and Bleeding Heart 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
Bahia Red is a moderately assertive species (5/10), while Bleeding Heart Tetra is peaceful (2/10). This modest difference means Bahia Red may occasionally assert dominance over Bleeding Heart Tetra.
Bahia Red and Bleeding Heart 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.
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 Bahia Red and Bleeding Heart 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 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
Both fish can tolerate a pH between 6 and 7.2. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 4–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Bahia Red and Bleeding Heart Tetra together, plan for an aquarium of at least 250 litres with a minimum length of 120 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), Driftwood (Digestion/Hiding), Plants - Densely covered, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Bahia Red is a plant destroyer, which conflicts with Bleeding Heart 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 Bahia Red and Bleeding Heart Tetra live together?
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 250 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do Bahia Red and Bleeding Heart Tetra need?
A minimum of 250 litres (tank length at least 120 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 Bahia Red and Bleeding Heart 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 Bahia Red or Bleeding Heart Tetra aggressive?
Bahia Red is moderately assertive (5/10) and Bleeding Heart Tetra is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Bahia Red and Bleeding Heart Tetra need?
Both species overlap in the 6–7.2 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Bleeding Heart Tetra nip Bahia Red's fins?
Bleeding Heart Tetra is a known fin nipper. If Bahia Red has long or flowing fins, there is a real risk of fin damage. Keeping Bleeding Heart Tetra in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Bahia Red's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Bahia Red 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.
