Cardinal Brachyrhaphis

Care requirements

Care level: Intermediate – Advanced.

The listed lifespan is up to 3 years.

Water parameters

The temperature range for this fish is 21–30 °C. Compare it carefully with the aquarium target temperature instead of assuming every tropical community setup is suitable.

The pH range for this fish is 6.5–8. That points to a broad freshwater range, but stability is more important than sudden corrections.

The GH range for this fish is 5–20 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.

Temperament and compatibility

Cardinal Brachyrhaphis needs more careful companion choice because the temperament data suggests space, boundaries, or similar-sized fish may matter.

Feeding

As an omnivore, Cardinal Brachyrhaphis should receive a varied diet rather than one repeated food type.

Before adding this fish

• Choose other fish with overlapping temperature needs.
• Keep pH stable within the listed range instead of making sudden corrections.
• Choose other fish carefully around this temperament.
• Offer a varied diet that matches this species.
