Black Marble Angel

Pterophyllum scalare, commonly known as the Black Marble Angel, is a striking freshwater angelfish native to the Amazon Basin, particularly found in Peru, Colombia, and Brazil. This species thrives in the complex ecosystems of swamps and flooded regions, where dense vegetation provides shelter and breeding grounds. Its unique coloration, featuring dark marbled patterns against a lighter background, makes it a favorite among aquarium enthusiasts.

In terms of appearance, the Black Marble Angel exhibits a graceful, triangular body shape with long, elegant fins that sway beautifully in the water. Adults can reach a maximum size of around 15 cm. Their color can vary from light to dark, with the marbled pattern providing each individual with a distinct look, making them a visually appealing addition to any aquarium.

Behaviorally, the Black Marble Angel is known for its calm and peaceful nature, although it can show territorial tendencies during breeding. They prefer to swim in the mid-levels of the aquarium and often engage in social interactions with tank mates. Their native habitats feature slow-moving waters, which are often rich in organic material, providing them with a diverse environment to explore.

The Black Marble Angel is typically found in waters with a neutral to slightly acidic pH, making it adaptable to various aquarium settings. Their preference for warm water temperatures, ranging from 26 to 30 °C, aligns with their natural habitat, where they thrive in stable environmental conditions. This adaptability and their captivating appearance make them one of the most sought-after species in the aquarium trade.

To maintain the health and vibrancy of Black Marble Angels, importers and retailers should ensure that water parameters closely mimic their natural habitat. The ideal temperature range is between 26.0 and 30.0 °C, with a pH level between 6.0 and 7.0. Water hardness should be maintained between 3 to 10 °dH to promote optimal health.

Feeding is relatively straightforward, as Black Marble Angels are omnivorous. A varied diet including high-quality flakes, pellets, and occasional live or frozen foods like brine shrimp will ensure their nutritional needs are met. It's important to avoid overfeeding, as this can lead to water quality issues.

Compatibility with other species is generally good, but caution should be taken with smaller fish, as they may be viewed as prey. Ideal tank mates include peaceful community fish that share similar water requirements. Acclimation is crucial; gradual introduction to the new environment over several hours will help reduce stress. Quarantine new arrivals for at least two weeks to prevent the spread of diseases to existing stock.

The Black Marble Angel is well-suited for shipping but requires careful handling to maintain water temperatures in transit. Packing density should allow for sufficient space to prevent stress during transport. It's important to maintain temperatures within their preferred range during shipping to minimize sensitivity. This species is not listed under CITES, simplifying export regulations.
