Cobalt Blue Goby

Care requirements

Care level: Beginner – Intermediate.

The listed lifespan is up to 5 years.

Water parameters

The temperature range for this fish is 20–28 °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 2–12 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.

The KH range is 2–6 dKH. Use it as a general stability reference rather than a reason for aggressive adjustments.

Temperament and compatibility

As a peaceful fish, Cobalt Blue Goby is best kept with calm species that will not harass it or dominate the feeding area.

Feeding

As an omnivore, Cobalt Blue Goby 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.
• Avoid aggressive or highly competitive fish.
• Offer a varied diet that matches this species.
