The Black Molly is a popular variation of the Molly fish, known for its dark black coloration and adaptable nature. It's an attractive and peaceful fish, commonly kept in community aquariums.

Key Characteristics:
Appearance: Black Mollies have a sleek, elongated body with solid black coloring. Their coloration can range from deep black to dark charcoal. Some individuals may have small white spots or silver sheen on their scales.
Size: They typically grow to about 3–4 inches (7.5–10 cm).
Lifespan: With proper care, they can live for 3–5 years.
Body Shape: The body is slender with a finnage that includes a triangular dorsal fin and a forked tail.
Water Parameters:
Temperature: They thrive in 75–80°F (24–27°C).
pH: They prefer slightly alkaline water, ideally around 7.5–8.5.
Hardness: 10–25 dGH (moderate to hard).
Ammonia/Nitrites: Both should be kept at 0 ppm. Regular water changes are essential for maintaining good water quality.
Tank Setup:
Tank Size: A minimum of 20 gallons is recommended for a small group of Black Mollies.
Filtration: Moderate filtration is needed as Mollies are sensitive to poor water quality. They benefit from a good filtration system to maintain healthy water conditions.
Substrate: Smooth gravel or sand is best, as it is easy to clean and won’t damage their fins.
Decor: Provide plenty of plants, driftwood, and hiding spots. Mollies prefer having space to swim but also appreciate areas for cover and shade.
Diet:
Omnivores: Black Mollies eat a varied diet, including both plant-based and protein-rich foods.
Flakes or pellets designed for livebearers should be the base of their diet.
Live/frozen foods such as bloodworms, brine shrimp, and daphnia are great protein sources.
Vegetables like blanched spinach, zucchini, and peas help with digestion.
Feeding Frequency: Feed small amounts 2–3 times a day, ensuring the food is consumed within a few minutes to avoid overfeeding.
Behavior and Tankmates:
Temperament: Black Mollies are peaceful, active, and social. They enjoy being in groups and are best kept in schools of 3 or more.
Tankmates: They are compatible with other peaceful fish such as neon tetras, guppies, corydoras, rasboras, and other mollies. Avoid aggressive species.
Community Tank: Due to their calm nature, they fit well in community tanks and can peacefully coexist with a variety of non-aggressive fish.
Breeding:
Black Mollies are livebearers, meaning they give birth to live fry rather than laying eggs.
Breeding process: Males typically chase females and engage in courtship behavior, displaying vibrant colors.
Fry: After 4–6 weeks, the female will give birth to 20-100 tiny fry. Fry can be kept in a separate breeding tank or protected by plants in the main tank to avoid predation from the adults.
Fry care: Feed the fry infusoria or finely crushed flake food until they are large enough to eat adult food.
Care Tips:
Perform regular water changes (20–30%) to maintain good water quality.
Ensure that water parameters remain stable and avoid rapid changes in temperature or pH.
Provide sufficient space and avoid overcrowding.
Keep an eye on the fish for signs of stress or disease, such as faded colors, sluggish behavior, or loss of appetite.
