Armoured Stickleback

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 5 years.

Water parameters

The temperature range for this fish is 22–27 °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 6.5–7.5. That points to slightly acidic to neutral water, but stability is more important than sudden corrections.

The GH range for this fish is 6–10 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.

Temperament and compatibility

As a peaceful bottom-to-middle swimmer, Armoured Stickleback is best kept with calm species that will not harass it or dominate the feeding area.

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

Use foods that suit a meatier diet and avoid combining it with fish small enough to be treated as food.

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.
• Avoid aggressive or highly competitive fish.
• Offer a varied diet that matches this species.
