Steel Blue Lyretail Killifish

Care requirements

Care level: Beginner – Intermediate.

Because it uses the lower to middle part of the aquarium, leave enough open substrate area instead of crowding that part of the aquarium.

The listed lifespan is up to 3 years.

Water parameters

The temperature range for this fish is 22–25 °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 6–7.5. That points to slightly acidic to neutral water, but stability is more important than sudden corrections.

The GH range for this fish is 5–12 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.

The KH range is 5–8 dKH. Use it as a general stability reference rather than a reason for aggressive adjustments.

Temperament and compatibility

Steel Blue Lyretail Killifish needs more careful companion choice because the temperament data suggests space, boundaries, or similar-sized fish may matter.

Because this fish uses the lower to middle part of the aquarium, compatibility is easier when other fish are not all competing for the same swimming space.

Swimming zone and behavior

This fish uses the lower to middle part of the aquarium, so leave enough open substrate area for movement and feeding.

Feeding

As an omnivore, Steel Blue Lyretail Killifish should receive a varied diet rather than one repeated food type.

Because it feeds near the bottom, make sure food reaches the substrate and is not completely taken by faster fish in the open water.

Before adding this fish

• Make sure the bottom area has enough open substrate for a group.
• 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 suitable for an omnivorous bottom-dwelling fish.
