Silver Angelfish: The Wild Type, and the First Ones I Bred
The phenotype every fancy variety was selected out of, and the one that spawned for me without my doing anything clever — in an unheated tank, with no conditioning regime and a clay roof tile for a slate.
| Scientific name | Pterophyllum scalare (domestic wild-type “Silver” phenotype) |
|---|---|
| Adult size | Body ~4–6 in; total height with fins 8–10+ in |
| Minimum tank | 29 gal tall (18 in) for a pair; 55+ gal for a small group |
| Water | 76–82°F (24–28°C), pH 6.5–7.5, soft to moderately hard |
| Temperament | Semi-territorial cichlid; peaceful when uncrowded |
| Diet | Quality pellets + frozen mysis/brine; occasional live |
| Lifespan | 10–15 years with proper care |
| Difficulty | Beginner–intermediate |
The Silver is the wild-type Pterophyllum scalare: not a variety that was bred for, but the fish every other variety was bred out of. Its care is the baseline the rest of this site's freshwater pages describe — size, water, tank mates and breeding are covered below.
It is also the first angelfish I bred. That happened in an unheated tank in Colombo with no conditioning regime, no live food cultures and an old clay roof tile in place of a spawning slate, which is to say it happened without much help from me. One spawn proves nothing by itself, and the section further down says so — but it is the reason I would point a first-time keeper at this fish rather than at something fancier.
Appearance & Size
The Silver Angelfish has a laterally compressed, diamond-shaped body that moves gracefully through aquatic plants. Its body is shimmering silver, accented by three distinct vertical black stripes, with a fourth, less prominent stripe often running through the eye. Long, elegant dorsal and anal fins complete the look and give the fish its significant height.
In a suitable environment, a Silver Angelfish will grow to about 6 inches in length, but its height, including fins, can reach an impressive 10 inches — a key reason taller aquariums are essential for their well-being.
Diet & Feeding
As omnivores, Silver Angelfish need a varied diet. A high-quality tropical flake or pellet should form the core, supplemented with:
- Frozen foods: brine shrimp, bloodworms, and mysis shrimp.
- Live foods: occasional daphnia or mosquito larvae, especially when conditioning for breeding.
- Vegetable matter: spirulina-based flakes or blanched spinach.
Feed adults once or twice a day, only as much as they can consume in 2–3 minutes to prevent overfeeding and protect water quality.
Tank Requirements & Water Parameters
Silver Angelfish come from slow-moving, densely planted waters in the Amazon basin, so replicating that habitat is key.
- Tank size: a 29-gallon high aquarium (18 in of height) is the minimum for a pair; 55 gallons or more for a small group.
- Filtration: a gentle but effective filter, such as a canister or hang-on-back with an adjustable outflow.
- Substrate & decor: fine, sandy substrate with driftwood and broadleaf plants like Amazon Swords and Java Fern for security and potential spawning sites.
- Water: 76–82°F (24–28°C), pH 6.5–7.5, soft to moderately hard.
Temperament & Ideal Tank Mates
Angelfish are cichlids with a semi-aggressive temperament that becomes more pronounced with age and during breeding, so choosing the right tank mates matters.
- Compatible: Corydoras catfish, larger tetras (Black Skirt, Rummy Nose), Rainbowfish, and Plecos.
- Avoid: fin-nippers like Tiger Barbs, and anything small enough to be eaten, such as Neon Tetras or guppies.

How to Breed Silver Angelfish
- Pairing: raise a group of 6–8 juveniles together and let them pair off naturally.
- Conditioning: feed the pair a high-protein diet of live and frozen foods to trigger spawning behavior.
- Spawning: the pair chooses and meticulously cleans a vertical surface — a broad leaf, slate, or filter intake. The female lays rows of eggs, and the male follows to fertilize them.
- Hatching: the parents fan the eggs to prevent fungus; eggs typically hatch in 2–3 days, with fry free-swimming about a week later.

The first angelfish I bred were silvers, and I doubt that was a coincidence. This was a hobby, not a project — an unheated tank in Colombo, no conditioning regime, no live food cultures, no proper spawning slate. I gave them an old clay roof tile that was lying around. They spawned anyway, on my first attempt.
One spawn proves nothing on its own, so take this for what it is. But silvers are the wild-type phenotype that every fancy variety was selected out of, and they have a long-standing reputation among hobbyists as the most forgiving of the lot — less far removed from the original fish than heavily line-bred veils and some of the darker strains. If you want a first spawn from fish that will tolerate you learning on them, this is the sensible variety to learn on.
What I'd change about how this page presents breeding — and most pages do the same — is the impression that spawning is the achievement. The four steps above are where all the detail goes, and in my case that part happened without me doing anything clever at all. Everything genuinely difficult came afterwards: I lost that entire first batch of fry within days of them hatching. If you're hoping for a first spawn, put your preparation into the tank the fry will go into, not into conditioning the adults. The breeding guide has what that cost me.
Common Health Issues
Silver Angelfish are hardy, but can be susceptible to common freshwater ailments, usually from stress or poor water quality.
- Ich (white spot disease): small white dots on fins and body; treatable with medication and by raising temperature.
- Fin rot: frayed or ragged fins from bacterial infection, almost always a result of poor water conditions.
The best prevention is pristine water quality through regular water changes and avoiding sudden swings in temperature or pH.
Buying Healthy Silver Angelfish
Healthy angelfish are active, alert, and swim confidently rather than hiding or acting lethargic. Bodies should be free of white spots, sores, or blemishes, with clear, bright eyes and fully extended, intact fins.
- Upright posture, intact fins, strong response to food
- Clear eyes, smooth opercula, no flashing or clamped fins
- Quarantine new arrivals 2–4 weeks

Frequently Asked Questions
Are “Silver” and “Wild” angelfish the same?
“Silver” is the domestic wild-type pattern of Pterophyllum scalare. Wild-caught fish look similar but may be more parameter-sensitive.
How many should I keep?
Keep one, a proven pair, or a larger group of six or more to diffuse aggression. Avoid groups of two or three.
Do they eat small tetras?
They may prey on very small fish. Choose mid-sized, non-nippy schooling fish instead.
