Gary Lange’s Rainbowfish

Care requirements

Care level: Beginner – Intermediate.

Because it uses the middle to upper part of the aquarium, leave enough open swimming space instead of crowding that part of the aquarium.

The listed lifespan is up to 8 years.

Water parameters

The temperature range for this fish is 25–28 °C, which fits many tropical freshwater aquariums. Choose other fish with overlapping temperature needs.

The pH range for this fish is 7–8. That points to neutral to slightly alkaline water, but stability is more important than sudden corrections.

The GH range for this fish is 5–15 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 middle-to-top swimmer, Gary Lange’s Rainbowfish is best kept with calm species that will not harass it or dominate the feeding area.

Because this fish uses the middle to upper 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 middle to upper part of the aquarium, so leave enough open swimming space for movement and feeding.

Feeding

As an omnivore, Gary Lange’s Rainbowfish 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.
