⚠️ Compatibility notes
Black Marble Angelfish are generally peaceful but may become territorial during maturity and breeding.
Not ideal with:
- Fin-nipping species
- Extremely tiny nano fish
- Hyperaggressive cichlids
- Overcrowded aquariums
Best suited for:
✔️ Peaceful tropical community aquariums
✔️ Planted display tanks
✔️ Angelfish-focused setups
✔️ South American aquascapes

Black Marble Angelfish (Pterophyllum scalare – black marble morph)
Description
The Black Marble Angelfish (Pterophyllum scalare – black marble morph), offered by Nero Labs, is a selectively maintained ornamental angelfish lineage recognized for its irregular dark marbling, contrasting silver-black pattern expression, and refined finnage structure. Derived from domesticated Amazonian angelfish lines, this morph combines the species’ characteristic laterally compressed body form with highly variable melanistic patterning unique to each individual.
Body coloration typically presents as a mixture of deep black, charcoal, silver, and smoky grey distributed in irregular marbled patches across the body and finnage. Pattern density and contrast vary naturally between individuals, ranging from heavily melanistic forms to balanced silver-black expressions with fragmented barring. Reflective iridescence may develop subtly under stable lighting and low-stress conditions. Extended dorsal and anal fins contribute to the species’ distinctive triangular silhouette and graceful midwater movement.
Behaviour is generally calm and socially structured, though territorial behaviour may emerge during pair formation, hierarchy establishment, or reproductive conditioning. Individuals display deliberate movement patterns and localized spatial awareness within community environments. Pattern clarity, finnage quality, and colour depth are strongly influenced by nutritional balance, environmental stability, and reduced chronic stress.
Specimens supplied are lab-reared and system-acclimated within controlled, closed-system environments, minimizing early-life stress and supporting predictable long-term adaptation to aquarium systems. This lineage represents domesticated ornamental stock maintained for pattern diversity, morphological stability, and aquarium suitability rather than wild ecological function or conservation deployment.
System & Rearing Notes
Origin: In-house, Nero Labs
Rearing environment: Controlled, closed system
Line status: Selectively maintained ornamental angelfish morph
Behaviour: Generally peaceful; territorial tendencies may emerge during breeding phases
Swimming profile: Midwater, slow and controlled movement patterns
Feeding behaviour: Omnivorous; accepts prepared, frozen, and live feeds
Habitat preference: Tall planted aquaria with vertical structure and low to moderate flow
Pattern development: Progressive; marbling intensity and contrast stabilize with maturity
Finnage development: Enhanced under low-stress conditions and stable nutrition
Minor variation in marbling density, melanistic coverage, and finnage proportions may occur between individuals and reflects normal biological diversity within maintained ornamental morphs.
Availability & Use
Availability of Black Marble Angelfish is cycle-dependent and determined by biological readiness rather than inventory-driven targets. This morph is suitable for beginner to intermediate aquarists capable of maintaining stable water quality and appropriately structured community systems.
Best suited for planted display aquaria, ornamental angelfish collections, and vertically structured freshwater layouts emphasizing contrast-rich patterning and elegant midwater movement.
Important Note
Black Marble Angelfish require adequate vertical swimming space and should not be housed with persistent fin-nipping species. Environmental instability or overcrowding may negatively affect finnage quality and colour contrast.
Ethical & Operational Context
Distribution of Black Marble Angelfish through Nero Labs prioritizes organism welfare, lineage integrity, and responsible propagation of selectively refined ornamental phenotypes. Proceeds support refinement of angelfish husbandry protocols, nutritional research, and applied ornamental aquaculture initiatives.
