Its small size and relatively easy care requirements make it perfect for well-maintained planted tanks and biotope setups.

Care Guide for Tefe Agassizii’s ‘Pearl Blue’ Dwarf Cichlid (Apistogramma agassizii Tefe ‘Pearl Blue’)

Tank Requirements:

• Tank Size: A minimum of 20 gallons for a pair is recommended. For a group or community setup, consider at least 30-40 gallons with ample space and hiding spots. These fish are territorial, especially during breeding, so a larger tank will help to reduce aggression.

• Water Parameters:

  • Temperature: 75°F – 82°F (24°C – 28°C)
  • pH: 5.5 – 7.0 (slightly acidic to neutral)
  • Hardness: 2 – 8 dGH (soft water preferred, mimicking their natural Amazonian environment)
  • Ammonia/Nitrites: Should always be 0 ppm, as Apistogramma are sensitive to poor water conditions.
  • Nitrates: Keep below 20 ppm with regular water changes.

• Filtration & Water Flow: Provide gentle water flow to mimic their natural slow-moving river habitats. Sponge filters or canister filters are ideal for maintaining clean, well-oxygenated water without creating strong currents.

• Water Changes: Regular, small water changes (20-30%) are essential to maintain stable water parameters and reduce the buildup of waste and nitrates. More frequent water changes may be necessary in smaller tanks or heavily stocked setups.

• Lighting: Moderate lighting is best for Apistogramma agassizii, especially if keeping them in a planted tank. Avoid overly bright lights as these fish prefer shaded areas.

• Substrate & Tank Decor:

  • Substrate: Fine, soft sand is preferred, as these cichlids enjoy sifting through the substrate for food. Sand also prevents injury to their delicate barbels.
  • Aquascaping: Create a natural habitat using driftwood, leaf litter, rocks, and live plants such as Amazon Swords, Java Fern, and Cryptocorynes. The dense cover provides hiding spots and mimics the fish’s natural environment.
  • Hiding Places: Use caves, coconut shells, or PVC pipe to create hiding spots and territories, especially if breeding pairs are kept in the tank.

Diet:

The Tefe Agassizii ‘Pearl Blue’ Dwarf Cichlid is an omnivore with a strong preference for live and frozen foods.

• Preferred Foods:
  • Frozen/live foods: Bloodworms, brine shrimp, daphnia, and blackworms are excellent choices.
  • High-quality pellets/flakes: Apistogramma will also accept high-quality sinking pellets or flakes designed for cichlids, though live or frozen foods should make up the bulk of their diet.
  • Vegetable matter: Occasionally supplement their diet with blanched spinach or spirulina to provide variety and balance.

Feed them small portions 2-3 times a day, and avoid overfeeding to maintain good water quality.

Behavior & Compatibility:

• Temperament: The ‘Pearl Blue’ Dwarf Cichlid is generally peaceful but can be territorial during breeding. They are more aggressive towards other bottom-dwelling or similarly sized species, especially other Apistogramma males. In larger, well-decorated tanks, aggression can be managed with multiple hiding spots and clear territorial boundaries.

• Schooling/Pairing: These fish are best kept in breeding pairs or harems (one male with multiple females) if the tank is large enough. Avoid keeping multiple males in small tanks unless there is sufficient space and decor to establish territories.

• Tank Mates:

  • Ideal tank mates: Small, peaceful fish such as Neon Tetras, Cardinal Tetras, Rummy Nose Tetras, Corydoras catfish, and Otocinclus make good companions.
  • Avoid aggressive or fin-nipping species, as well as other territorial bottom-dwelling cichlids that could compete with them.
  • Ensure tank mates can tolerate soft, slightly acidic water and do not stress out the Apistogramma.

Breeding:

The ‘Pearl Blue’ Dwarf Cichlid is a cave-spawning species and can be bred in home aquariums with the right conditions.

• Breeding Setup:

  • Use a separate breeding tank (15-20 gallons) with soft, acidic water (pH around 5.5-6.5) and a temperature of 80°F – 82°F (27°C – 28°C).
  • Provide caves, flower pots, or coconut shells where the female can lay her eggs. Males will guard the territory but leave the raising of the fry to the female.

• Courtship & Egg Laying: The male will court the female, and if successful, the female will lay her eggs inside the cave or hiding spot. She will guard the eggs and fry while the male defends the territory.

• Fry Care: Once the fry hatch, they can be fed with infusoria or newly hatched brine shrimp. As they grow, gradually introduce them to finely crushed flakes or pellets. Ensure frequent small water changes to maintain water quality in the fry tank.

Health Considerations:

• Common Issues: Apistogramma can be prone to certain health issues if not provided with stable water conditions, including:

  • Ich (white spot disease)
  • Bacterial infections
  • Parasitic infestations (such as gill flukes or skin worms)

• Prevention: Maintaining pristine water quality, offering a varied and nutritious diet, and performing regular water changes are essential to keeping your Apistogramma healthy. Quarantine new fish and avoid sudden fluctuations in water parameters.

• Signs of Stress or Illness:

  • Lethargy or hiding more than usual
  • Faded coloration or clamped fins
  • Rapid gill movement or scratching against surfaces
  • Loss of appetite

Special Considerations:

• Sensitive to Water Parameters: These fish are sensitive to fluctuations in water chemistry, especially pH and hardness. Consistency is key. Keep the water slightly acidic and soft to replicate their natural habitat.

• Acclimation: When introducing Tefe Agassizii to your tank, perform a slow drip acclimation to allow the fish to adjust to the water conditions without stress.

Summary:

The Tefe Agassizii’s ‘Pearl Blue’ Dwarf Cichlid is a beautiful, rare fish with striking iridescent blue and pearlescent tones, making it a prized addition to any well-planned aquascape. With their small size, vibrant colors, and fascinating behavior, they are ideal for aquarists looking for a peaceful, show-stopping fish. Their care requires attention to detail, particularly in water quality and tank setup, but they are relatively easy to care for in a well-maintained, planted aquarium. Whether you’re interested in breeding or simply adding a touch of color to your community tank, these cichlids are sure to impress.
