Marble Angel (2.5-3”)

Scientific Name:

Pterophyllum scalare (Marble Variant)

Maximum Size and Lifespan:

• Size: Up to 6 inches (15 cm) in body length; with fins, height can reach 8–10 inches (20–25 cm)

• Lifespan: Typically 8–10 years in captivity possibly longer with proper care

Recommended Aquarium Size:

• Minimum Tank Size: 30-40 gallons for a single adult; 55-75+ gallons or more for a group or with other fish

• Tank Height: Tall tanks are preferred due to their vertical body shape

Water Changes and General Care:

• Water Temperature: 76–82°F (24–28°C)

• pH Range: 6.5–7.5

• Water Changes: 25–50% weekly; more if the tank is heavily stocked

• Filtration: Moderate to strong, but avoid excessive current

• Aquascaping: Include vertical plants, driftwood, and open swimming space

Tankmates:

Marble Angelfish are generally peaceful, but can show mild territorial behavior, especially when spawning. Ideal tankmates include:

• Corydoras, Plecos, Tetras (larger varieties like Rummy Nose or Congo Tetras), Gouramis, Bosemani Rainbows, Electric Blue Acara(With Caution)

• Avoid: overly small fish (like Neon/Cardinal Tetras), or aggressive cichlids

Diet:

Omnivorous—offer a varied and balanced diet:

• Staples: High-quality flakes or pellets (specifically for cichlids or angelfish)

• Frozen: Bloodworms, brine shrimp

• Feeding Frequency: 1–2 times daily with 1 day to fast to avoid bloating

Overview:

Marble Angelfish are a selectively bred color variant of the wild Pterophyllum scalare, known for their unique marble patterning, graceful, disc-shaped body. They are intelligent, personable, and form strong pair bonds, making them favorites in the hobby. With appropriate tank size, stable water conditions, and a peaceful community, they thrive and display their best colors and behavior.

Natural Environment:

Though the Marble variety does not exist in the wild, Pterophyllum scalare originates from the Amazon River Basin (especially in Peru, Brazil, and Colombia), where they inhabit:

• Slow-moving waters like floodplains and quiet tributaries

• Areas dense in submerged vegetation and leaf litter

• Warm, soft, acidic water conditions

Breeding:

• Breeding Setup: Use a separate 20–30 gallon breeding tank with a flat vertical surface (like a slate or Cone)

• Pair Formation: Angelfish form monogamous pairs; it's best to let pairs form naturally from a group

• Spawning Behavior: The female lays eggs in rows; the male fertilizes them. Both parents guard the eggs.

• Egg Care: Eggs hatch in 2–3 days; fry become free-swimming in about 4-7 days

• Feeding Fry: Start with Live baby brine shrimp and crushed flake/pellets once they grow.
