Tank Requirements for Black Marble Angelfish 3.5-4cm

Even as juveniles, Black Marble Angelfish benefit from a well‑planned tank:

Recommended tank size: a tall aquarium from around 3ft+ is ideal for a small group as they grow
Filtration: reliable filtration with gentle to moderate flow (they dislike strong current)
Décor: vertical plants, driftwood and open swimming spaces
Substrate: sand or fine gravel, with plants or hardscape for security

A calm, well‑scaped tank helps your Black Marble Angelfish 3.5-4cm settle quickly and show natural behaviour.

Water Parameters (Guide Only)

Black Marble Angelfish are reasonably adaptable if changes are slow and water quality is high:

Temperature: around 24–28°C
pH: roughly 6.5–7.5
Hardness: soft to moderately hard water
Ammonia & Nitrite: 0 ppm
Nitrate: kept low with regular water changes

Stable, clean water is more important than chasing exact numbers. Good maintenance supports healthy growth for your Black Marble Angelfish 3.5-4cm.

Feeding Black Marble Angelfish

The Black Marble Angelfish 3.5-4cm is an omnivore and enjoys a varied diet:

Quality micro pellets or fine flakes suitable for juvenile tropical fish
Frozen or live foods such as baby brine shrimp, daphnia and finely chopped bloodworms
Occasional vegetable‑based foods or spirulina‑rich options

Feeding small amounts 2–3 times per day helps juvenile Black Marble Angelfish grow steadily and maintain good condition.

Behaviour and Tank Mates

Black Marble Angelfish are generally peaceful to semi‑territorial cichlids:

Behaviour: calm, graceful swimmers that may become more territorial as they mature, especially if pairing
Best kept: in small groups of juveniles in a suitably sized tank
Tank mates: peaceful community fish that are not fin‑nippers and are too large to be seen as food

Good tank mate options can include larger tetras, peaceful barbs, rainbowfish, Corydoras and some smaller peaceful cichlids, depending on tank size and layout. Avoid very small fish and aggressive fin‑nippers that may damage the fins of your Black Marble Angelfish 3.5-4cm.

Important Notes

The Black Marble Angelfish 3.5-4cm will grow – plan for their adult size and a suitably tall aquarium.
Provide stable water conditions, good filtration and regular maintenance for long‑term health.
Individual temperament can vary – always monitor interactions as they mature and form hierarchies or pairs.
