Size

The Rainbow Shark is a bold and active freshwater fish recognised for its dark body and striking red fins. Despite its name, it is not a true shark, but its streamlined shape and territorial nature give it a strong presence in the aquarium.

Rainbow Sharks are best suited to larger, well-structured tanks where they can establish territories without constant conflict. When housed correctly, they are hardy, long-lived, and make an impressive feature fish for semi-aggressive freshwater setups.

Physical Characteristics:

  • Adult Size: 12–15 cm

  • Body Shape: Streamlined, shark-like profile

  • Colouration: Dark grey to black body with vivid red fins

  • Sexual Dimorphism: Minimal; females may appear slightly fuller-bodied

  • Lifespan: 5–8 years

Behaviour & Temperament:

  • Temperament: Semi-aggressive

  • Swimming Level: Bottom to mid levels

  • Territorial Behaviour: Strong, especially toward similar-shaped fish

  • Social Behaviour: Best kept singly

Rainbow Sharks become increasingly territorial as they mature and should not be housed with other sharks or similar bottom-dwelling species.

Aquarium Requirements:

  • Minimum Tank Size: 120 litres

  • Water Temperature: 22–28°C

  • pH Range: 6.5–7.5

  • Water Hardness: 5–15 dGH

  • Water Flow: Moderate

  • Substrate: Sand or smooth gravel

  • Aquascape: Driftwood, rocks, caves, and broken sight lines

  • Tank Cover: Recommended

Feeding:

Rainbow Sharks are omnivorous and require a varied diet:

  • Sinking pellets or wafers

  • Algae wafers

  • Blanched vegetables (zucchini, spinach)

  • Frozen foods (bloodworms, brine shrimp)

Feed once daily and avoid overfeeding.

Compatibility:

Suitable Tank Mates:

  • Large tetras

  • Rainbowfish

  • Barbs (non fin-nipping species)

  • Gouramis

  • Fast mid-to-upper level fish

Avoid Housing With:

  • Other sharks or loaches

  • Corydoras and other bottom dwellers

  • Slow or long-finned fish

  • Small, timid community species

Breeding:

  • Breeding in Captivity: Extremely rare

  • Commercial Breeding: Hormone-assisted

  • Notes: Not suitable for home breeding

Special Considerations:

  • Must be kept singly

  • Territorial behaviour increases with age

  • Requires space and hiding areas to reduce aggression

  • Not suitable for small or peaceful community aquariums
