Polleni Paratilapia Cichlid

Introduction: The Polleni Cichlid, also known as the Paratilapia Polleni or the Black Diamond Cichlid, is a strikingly beautiful and intriguing fish native to Madagascar. Known for its velvety black body adorned with iridescent blue, green, or white spots, this cichlid is a favorite among advanced aquarists due to its unique appearance and relatively large size. Polleni Cichlids are hardy, intelligent, and exhibit fascinating behaviors, making them a rewarding species to keep in larger tanks.

Scientific Name: The Polleni Cichlid is scientifically known as Paratilapia polleni. It is commonly referred to as the Polleni Cichlid, Black Diamond Cichlid, or Starry Night Cichlid due to its star-like spots.

Water Quality and Temperature: To ensure the health and vitality of your Polleni Cichlid, maintain the following water parameters:

• Temperature: Keep the water temperature between 74°F to 82°F (23°C to 28°C).
• pH Level: Maintain a pH level between 6.5 and 7.5, replicating their natural slightly acidic to neutral water conditions.
• GH Level: Aim for a general hardness (GH) level of 6 to 12 dGH.
• KH Level: Keep the carbonate hardness (KH) within the range of 4 to 8 dKH for stable water conditions.

Feeding: Polleni Cichlids are carnivorous with an omnivorous tendency and enjoy a protein-rich diet. Provide the following:

• Pellets: High-quality cichlid pellets designed for large carnivorous cichlids.
• Live or Frozen Foods: Offer live or frozen foods like bloodworms, brine shrimp, krill, or earthworms to meet their protein needs.
• Occasional Vegetables: You can occasionally provide blanched vegetables such as spinach or peas for fiber and variety.
• Insects and Small Fish: In their natural environment, Polleni Cichlids prey on small fish and insects, so occasional live food offerings can stimulate natural hunting behaviors.

Tank Mates: The Polleni Cichlid can be territorial, especially during breeding, and may not tolerate other fish in smaller tanks. However, in a large aquarium, they can coexist with similarly sized, robust tank mates. Suitable companions include other large cichlids such as Green Terrors, Oscar fish, or Jack Dempseys. Avoid small or overly peaceful species, as they may be seen as prey. It is important to provide plenty of space and hiding spots to reduce aggression.

Substrates and Tank Decorations: A sandy or fine gravel substrate is ideal for the Polleni Cichlid. These cichlids enjoy digging, so avoid sharp or jagged substrates that could injure them. Incorporate plenty of rocks, caves, and driftwood to create hiding places and establish territories. Polleni Cichlids prefer structured environments where they can hide and feel secure, especially when breeding.

Suitable Plants: Polleni Cichlids may uproot delicate plants due to their digging behavior, so it’s best to use hardy, rooted plants like Anubias or Java Fern, which can be attached to rocks or driftwood. Floating plants such as water lettuce or duckweed can also help provide additional cover and shade, adding to the tank’s natural feel.

Sexing: Sexing Polleni Cichlids can be challenging as males and females look very similar. However, males tend to be slightly larger, more colorful, and may exhibit more prominent fin extensions. During breeding, females often take on a slightly plumper appearance.

Breeding: Breeding Polleni Cichlids can be achieved in captivity if the conditions are right. They are substrate spawners, meaning they will lay eggs on flat surfaces such as rocks or caves. The female guards the eggs while the male defends the territory. The fry will hatch after a few days and are free-swimming within a week. Providing a spacious, stable environment with plenty of hiding spots can encourage successful breeding. It’s important to monitor the pair, as males can sometimes become aggressive toward females during breeding.

Maximum Size and Longevity: Polleni Cichlids can grow to a maximum size of about 10 to 12 inches (25 to 30 cm) in length. With proper care, they can live for 10 to 12 years in captivity.

General Information: The Polleni Cichlid is a striking and formidable fish that requires a spacious, well-decorated aquarium to thrive. Due to their territorial nature and potential size, they are best suited for experienced aquarists with larger tanks. Their beautiful iridescent spots, intelligence, and fascinating behaviors make them a popular choice for those looking to add a bold centerpiece to their aquarium.

A Fun Fact: The Polleni Cichlid’s unique iridescent spots become more pronounced and vibrant when the fish is excited or in breeding condition, adding to its already captivating appearance. This shimmering effect gives the fish its nickname, the “Starry Night Cichlid.”
