Albino Corydoras care guide
Albino Corydoras (Corydoras aeneus var. albino) — minimum tank 60 L, temperature 22-28 °C, pH 6-8.
Compiled by Aquairi from published sources · Published · Updated
Overview
The Albino Corydoras is a colour variant of Corydoras aeneus (Bronze Corydoras) selectively bred for an absence of dark pigment. It retains all care requirements of the wild form: a hardy, peaceful armoured catfish from northern South America.
Taxonomy
- Family: Callichthyidae
- Genus: Corydoras
- Scientific name: Corydoras aeneus var. albino
- Common synonyms: Albino Cory
Habitat
The wild form is widespread in slow-flowing streams, swamps and shallow ponds from Trinidad and the Guianas south through the Amazon and La Plata drainages.
Tank requirements
- Minimum tank volume: 60 L (15.9 US gal)
- Adult size: 5-7 cm
- Temperature: 22-28 °C (72-82 °F)
- pH: 6-8
- GH: 2-20 °dGH
- Water flow: low
- Lifespan: 5-8 years
- School size: ≥6 individuals
Diet
An omnivorous bottom feeder. Offer sinking pellets, granules and a variety of small live or frozen foods (bloodworms, daphnia, brine shrimp). Sand substrates allow the species to forage naturally without damaging its barbels.
Compatibility
A peaceful shoaling fish that should be kept in groups of at least six. Compatible with a wide range of peaceful community species; avoid keeping with large or aggressive cichlids.
Breeding
Egg-laying. Cool water changes and conditioning on live foods stimulate spawning; adhesive eggs are placed on glass and broad leaves. The albino variant breeds as readily as the wild form.
Albino Corydoras Breeding Guide
Overview
The albino corydoras is an albino colour form of the bronze corydoras (Corydoras aeneus), distinguished by a pale pink or orange body and red eyes. The species ranges across South America east of the Andes, from Colombia and Trinidad to the Rio de la Plata basin, and breeds in captivity in the same way as the wild type via the T-position.
Sexing
Females tend to grow larger and become noticeably rounder and broader-bodied than males, especially when gravid; the higher body frame reflects the larger abdominal region. The albino form is sexed by the same body cues, since colour is not a guide.
Conditioning
Condition the group on a varied diet of live and frozen foods. Use a male-to-female ratio of about 2:1 to improve fertilisation.
Breeding Setup
Trigger spawning with a substantial 50-70% water change using cooler water while increasing oxygenation and flow, repeating daily until the fish spawn. Maintain general parameters of about 21-27 C, pH 6.0-8.0 and moderate hardness.
Spawning Behavior & Trigger
In the T-position the male presents his flank and the female attaches to his vent; an egg clutch is fertilised by a single male, and females spawn multiple small clutches at a time. Eggs are typically deposited on the glass, though fine-leaved plants or spawning mops are also used. A single spawning can produce up to about 200 eggs.
Egg & Fry Care
After spawning, remove either the adults or the eggs; eggs can be gently rolled up the glass with a finger and moved to a container with matching, well-oxygenated water. Incubation is normally 3-4 days; once the yolk sacs are absorbed the fry accept small live foods such as microworm and Artemia nauplii, and do better over a thin sand layer.
Common Challenges
Fungus on eggs is common; many breeders use methylene blue or alder cones to protect a clutch. Some albino lines descend from inbred stock and may show slower-growing or weaker fry, so introducing unrelated breeders helps maintain vigour.
Breeding Bronze Corydoras
Overview
The Bronze Corydoras (Corydoras aeneus) is an egg-scattering callichthyid catfish of intermediate breeding difficulty. It is one of the more readily bred Corydoras, spawning on the aquarium glass and plants after a cool-water trigger.
Sexing
Females are larger and noticeably rounder and broader-bodied than males, especially when gravid. A breeding group works best at a ratio of about two males per female.
Conditioning the Breeders
Condition the group well so that females fill with eggs. When they look ready, the spawning trigger is a large 50-70% water change with cooler water, plus increased oxygenation and flow, repeated daily until the fish spawn.
Spawning Behavior
Eggs are normally deposited on the aquarium glass, though it is recommended to also provide fine-leaved vegetation or fine spawning mops as alternative sites. The fish do not guard the eggs, so the cool-water change is repeated daily until a spawn is achieved and the eggs are then managed by the keeper.
Egg & Fry Care
After spawning, remove either the adults or the eggs; eggs deposited on the glass can be gently rolled up it with a finger and transferred. Many breeders add methylene blue, or an alder cone or two, to the rearing container to prevent fungal growth on the developing eggs. Incubation is normally 3-4 days. Once the fry have fully absorbed their yolk sacs they accept small live foods such as microworm and Artemia nauplii, and they do best reared over a thin layer of sand rather than in a bare-bottomed arrangement.
Common Challenges
Egg fungus is the main risk, addressed with the anti-fungal additions noted above and clean water. Adults will eat the eggs if left with them, so separating either the eggs or the spawners promptly after spawning is advised, and a male-biased group helps ensure that ripe females are fertilised.
