Angelfish types, decoded in 30 seconds
An aquarium label can put three different facts into one name:
- Species — for example, Pterophyllum scalare or Pterophyllum altum.
- Colour or pattern — for example, silver, black, marble, koi or platinum.
- Fin form — for example, standard fins or longer veil-type fins.
That is why “koi veil angelfish” should not be read as a fourth species. It is usually a domestic P. scalare described by pattern and finnage. A University of Florida extension publication explicitly separates colour patterns from veil and superveil fin varieties, but a shop label still cannot prove an individual fish's genotype or pedigree [3].
| Name layer | What it can tell you | Examples | What it cannot prove |
|---|---|---|---|
| Species | The taxonomic identity stated by the seller | P. scalare, P. altum, P. leopoldi | That a photograph or common name is correctly identified |
| Colour or pattern | The appearance a breeder or retailer intends to describe | Silver, marble, koi, platinum, black, zebra | Pedigree, health, adult size, temperament or rarity |
| Fin form | The intended fin shape or length | Standard, veil, superveil | That fins are undamaged or that a tank is safe for them |
| Size or grade | The seller's current sale-size band | Small, medium, large, pair | Adult size, age, sex or a universal centimetre value |
Freshwater or marine? Resolve that first
The search word angelfish is ambiguous. Freshwater angelfish are South American cichlids in the genus Pterophyllum. Marine angelfish are reef fish in the family Pomacanthidae; OATA lists emperor, majestic and regal angelfish among that saltwater group [7].
They share a common name, not an aquarium. A freshwater Pterophyllum page should show tall, laterally compressed cichlids and freshwater care. A marine page should state saltwater requirements and an exact reef-fish species. If a search result or listing does not make that boundary clear, do not use the picture alone to decide.
This guide covers freshwater angelfish only.
The three freshwater angelfish species
Eschmeyer's Catalog of Fishes currently records three valid Pterophyllum species: P. altum, P. leopoldi and P. scalare [1]. That scientific count is different from a retailer's list of colour varieties.
| Species | How to use the name | Buying boundary |
|---|---|---|
| Pterophyllum scalare | The common freshwater angelfish and the usual base for familiar domestic colour and fin labels | Confirm the exact variety, sale size and visible fish; do not turn colour into a new species |
| Pterophyllum altum | A separate valid species, not a premium colour of scalare | Use our Altum Angelfish UK guide before treating it as interchangeable with domestic scalare |
| Pterophyllum leopoldi | A separate valid species that is much less familiar in ordinary retail searches | Require a scientific-name listing and credible provenance; a small or striped fish is not identification proof |
FishBase describes wild-type P. scalare as a compressed, deep-bodied fish with a silver body and dark vertical bars [2]. Domestic breeders have selected many different appearances from aquarium lines. The extension record identifies silver, black marble, black lace, black and zebra among colour-pattern varieties, and veil and superveil as fin varieties [3].
Common Pterophyllum scalare colour and fin labels
These are practical visual descriptions, not a promise that every retailer applies an identical genetic standard.
| Label | Typical visual cue | Care decision |
|---|---|---|
| Silver | Silver body with strong vertical bars; closest visual shorthand to the wild-type pattern | Use the P. scalare care baseline; the word silver is not proof of wild origin |
| Zebra | A silver-like fish described with additional or narrower vertical bars | Count the visible pattern only as appearance; verify the scientific name separately |
| Black | A dark charcoal-to-black body | Do not infer sex, age, health or hardiness from colour |
| Marble | Irregular dark and light marbling rather than a fixed set of clean bars | Expect individual variation; a listing image may be representative rather than the exact fish |
| Koi | Usually a pale ground with black marbling and orange-to-red head or body colour | Koi is established current aquarium-trade language, but the label alone does not prove genotype [4] |
| Platinum | A pale silver-white appearance with little dark pattern | Confirm the actual listing photo and do not confuse a pale fish with a health diagnosis |
| Veil | Longer dorsal, anal and caudal finnage; it may be combined with any colour label | Plan around fin-nipping fish, sharp decor and excessive flow; veil is a fin form, not a species |
When a name is complicated, find the scientific species first, then the colour or pattern, then the fin form, then the sale size. If one of those facts is missing, ask rather than filling the gap from a stock photograph.
Which type should you choose?
Start with the visual result you enjoy, then make the welfare decision from the species and the exact fish.
| If you prefer… | Compare first | Check before buying |
|---|---|---|
| A classic barred freshwater-angelfish look | Silver and zebra labels | Whether the listing states P. scalare and shows the expected visible bars |
| An irregular, high-contrast pattern | Marble and koi labels | Whether the displayed fish is representative or the exact individual; koi orange can vary |
| A simple pale display fish | Platinum labels | Clear eyes, intact fins, normal swimming and accurate white balance in the image |
| A dark silhouette | Black labels | Visible fin edges and body condition; dark exposure should not hide damage |
| Dramatically extended fins | Veil combinations | Tank height, decor, flow and companions that will not damage long fins |
| A separate wild-species project | Altum or leopoldi listings | Scientific identity, provenance and species-specific care before price or appearance |
There is no evidence-based “prettiest” variety, and there is no stable worldwide “rarest” winner. Those are subjective or market-dependent claims. Availability changes, and a fashionable name can be applied more broadly than a breeder standard. The honest comparison is the exact visible fish, its stated scientific name and the evidence attached to the listing.
Can different colour types live together?
If the fish are domestic P. scalare colour forms, colour is not a compatibility rule. They share a species-level husbandry baseline, but they remain social cichlids whose behaviour can change with maturity, pairing and territory. A review of angelfish behaviour links social, reproductive, feeding and environmental conditions to welfare; it does not support choosing a community by colour [6].
Use the same checks you would use for any angelfish group:
- plan for the adult body and full fin height, not the juvenile sale photograph;
- provide a mature, filtered aquarium with stable tested water;
- watch whether every fish can feed and use space without repeated pursuit or cornering;
- keep a divider or suitable separate aquarium available if a pair forms or conflict persists;
- do not assume P. altum or P. leopoldi can simply replace a domestic scalare in the same plan.
OATA gives at least 120 litres as a broad floor for a pair of smaller American cichlids, says angelfish need sufficient height when fully grown, and recommends 40 litres per adult for shoaling angelfish [5]. Those figures are starting screens, not permission to ignore footprint, usable height, filtration, group dynamics or other occupants. Our Angelfish Care UK guide owns the full housing and husbandry decision; our Angelfish Tank Mates guide owns compatibility.
How to check a real listing before buying
Use this sequence on any UK retailer, including us:
- Find the scientific name. If it says only “angel,” establish freshwater versus marine and the actual species.
- Separate the label layers. Identify which words describe species, colour or pattern, fin form and sale size.
- Inspect the exact evidence. Check whether the image is the actual fish, the actual batch or only a representative example.
- Read the variant. Sale size, quantity and availability belong to the current product option, not to an evergreen guide.
- Check welfare markers. Look for clear eyes, intact scales and fins, steady breathing and appropriate swimming. OATA advises not buying from a tank containing visibly sick fish [5].
- Check the adult plan. Match the species to the aquarium's dimensions, water, social plan and existing livestock.
- Ignore unsupported shortcuts. “Rare,” “premium,” “easy,” “pair” and a high price do not establish lineage, sex, compatibility or health.
A pale platinum fish can be healthy, while a pale fish sold under another label may be stressed; a dark black variety can be healthy, while darkening in another fish may accompany a change in condition. Judge the stated variety alongside eyes, fins, scales, breathing, swimming and the condition of the whole retail tank.
Current angelfish for sale
This page explains names; it does not freeze products, prices or availability into editorial copy. Use the live Angelfish shop for the current range, exact product photographs, sale sizes, prices and stock. Then return to the decoder above if a listing combines terms such as koi, marble, platinum or veil.
For deeper decisions:
- Angelfish Care UK — aquarium, water, feeding, social behaviour and long-term care.
- Koi Angelfish UK — the koi appearance and its label boundaries.
- Altum Angelfish UK — the separate Pterophyllum altum species.
- Angelfish Tank Mates UK — adult-size, water, behaviour and exit-plan checks.
The live shop is the source of current commercial truth. This guide remains useful when stock changes because species, appearance and finnage are kept separate from temporary availability.
