Apistogramma Borellii

Meet the Apistogramma Borellii, Sp. Opal—the opal-toned dwarf cichlid that brings color, personality, and natural behavior to compact freshwater landscapes. This morph blends delicate iridescence with a confident, engaging presence, making it a standout choice for planted nano tanks and community setups alike.

What makes the Opal morph special

• Distinctive opal coloration with a soft iridescent sheen that shifts with light, paired with subtle, contrasting fins to create a captivating focal point in any aquarium.
• Compact adult size—typically 3–4 cm (about 1.2–1.6 inches)—perfect for smaller tanks without sacrificing visual impact.
• Adaptable care profile suited for soft to moderately soft water and a wide pH range (roughly pH 5.5–7.5), thriving in planted environments with gentle filtration.
• Breeding appeal—a rewarding dither-and-destiny experience for hobbyists who enjoy watching mating rituals, egg care, and fry-rearing up close.

Care and habitat

Opal Borellii thrives in a softly planted aquarium that mimics their natural habitat—dimly lit, with leaf litter, driftwood, and secure hiding spots. Provide a sandy or fine substrate for easy digging and encourage natural behavior like foraging along the bottom. Aim for a calm environment with gentle water movement to keep both adults and fry comfortable.

• Tank size: A pair is well-suited to a 20-gallon (80 L) setup or larger; smaller systems can house one individual comfortably, but a pair showcases their breeding behavior most vividly.
• Decor: Use dense plants, driftwood caves, and clay pots or slate tiles to create secure territories and spawning surfaces.
• Water parameters: Temperature in the mid-70s to high-70s °F (24–26°C), soft to moderately soft water, and a stable pH within the 5.5–7.5 range.
• Filtration: Gentle filtration with reliable water quality is key; keep currents mild to avoid stressing the fish while still maintaining clear water.

Diet and feeding

Apistogramma Borellii, Sp. Opal is omnivorous and appreciates a varied diet. Feed small portions multiple times a day to mimic natural feeding patterns and support color development. Good options include high-quality flaky or pellet foods, finely chopped frozen foods, and occasional live offerings such as baby brine shrimp or drozen daphnia. Monitor feeding to prevent uneaten food from clouding the tank.

Behavior and compatibility

In the tank, Opal Borellii is lively without being aggressively dominant. They establish clear territories, especially during breeding, but are generally compatible with other small, peaceful fish in a well-planted environment. Avoid keeping them with boisterous tankmates that may harass or outcompete them for hiding spaces. A paired setup rewards observers with vivid coloration changes during courtship and egg care.

Breeding and raising fry

Breeding is a highlight for this species. A well-maintained, stable community or species-specific setup encourages a healthy pair to form. The female typically lays eggs on a flat surface—such as a broad plant leaf, slate, or ceramic dish—while the male defends and fans the eggs. After hatching, fry become free-swimming in about a week; begin with infusoria or liquid fry foods, then transition to newly hatched live foods as they grow. With patient hands-on care, fry can become attractive adults that preserve the Opal morph’s signature coloration.

Who this is ideal for

• Keepers of nano and small planted tanks who want a striking, manageable centerpiece fish.
• Aquarists seeking a rewarding breeding project with visible parental care.
• People exploring peaceful dwarf cichlids that balance color, behavior, and easy care when provided with stable water conditions.

With its luminous Opal coloration, compact size, and engaging personality, the Apistogramma Borellii, Sp. Opal offers a distinct, low-ambition entry point into dwarf cichlid keeping while delivering rich visual interest and meaningful behavioral dynamics to your freshwater aquarium.
