Albino Bronze Cory (Osteogaster aenea; formerly Corydoras aeneus) is a peaceful shoaling bottom-dweller. Keep 6+ on smooth sand in a clean, oxygen-rich aquarium of about 80L or larger.
Adult size is the maximum length this species reaches at full maturity (scientific sources). The livestock you receive will be younger and smaller — pick a size variant above for the actual shipping size. Product-photo provenance and any image-specific limitations are stated on the listing.
Albino Bronze Cory are a shoaling species — they need 6+ to feel safe and show their full colour.

Identify the exact cory catfish before choosing care. Our starting policy for many common medium species is six compatible conspecifics, a mature 60 x 30 cm aquarium of about 60 litres, smooth fine sand and measured species-appropriate water.
Maintain these water conditions for optimal health and vibrant colors
Albino Bronze Cory is the familiar pale, red-eyed domestic pigmentation form of the Bronze Cory. Its accepted scientific name is Osteogaster aenea; many aquarium books, shops and fishkeepers still know the species by its former name, Corydoras aeneus. Albino Cory, Albino Corydoras and Albino Bronze Cory are trade names for this form, not separate species or subspecies.
This peaceful cory catfish spends much of its time foraging over the aquarium floor, resting with companions and making occasional trips to the surface for air. It should be chosen for its social behaviour rather than as a cleaner: it needs a proper group, its own food and the same regular aquarium maintenance as every other fish.
| Accepted scientific name | Osteogaster aenea |
|---|---|
| Familiar former name | Corydoras aeneus |
| Form | Domestic albino pigmentation form of the Bronze Cory |
| Expected adult size | Up to approximately 7.5 cm |
| Minimum aquarium | About 80 litres, with a base around 80 × 30 cm or larger |
| Social group | At least 6 of its own kind; allow more floor space for a larger group |
| Temperature | 22–27°C |

| Temperament | Peaceful, social bottom-dweller |
| Diet | Omnivorous; requires targeted sinking foods |
Choose an established aquarium of at least 80 litres with a base around 80 × 30 cm. Floor area matters more than height because the group feeds, explores and rests mainly along the bottom. A larger footprint is needed when keeping more fish or adding other bottom-dwelling species.
Smooth sand is the preferred substrate. Very fine, rounded gravel can also work if it is kept clean, but sharp or abrasive gravel should be avoided. Albino Corydoras search through the upper surface with sensitive barbels; rough material, trapped waste and neglected substrate can contribute to wear and infection. Leave open feeding areas and add plants, smooth wood or other shaded retreats without crowding the whole floor.
Use mature biological filtration and maintain zero ammonia and nitrite. Regular partial water changes, careful gravel or surface cleaning and sensible stocking help control waste. Gentle to moderate circulation is suitable when it keeps the water well oxygenated without pinning the fish against the substrate. Stability is more important than repeatedly adjusting the aquarium to chase a precise pH reading.
Surface-breathing warning: Corys are adapted to take occasional gulps of atmospheric air, so keep an unobstructed route to the water surface and do not cover it completely with floating plants. Brief, occasional surface visits can be normal. Repeated or frantic surfacing, rapid breathing, inactivity or loss of appetite requires immediate checks of temperature, oxygenation, ammonia, nitrite and general water quality.
Offer a complete sinking catfish pellet, tablet or wafer as the staple diet. Add variety with suitable frozen or thawed foods such as daphnia, brine shrimp or bloodworm in modest portions. Place food where the whole group can reach it and watch them eat, especially when fast midwater fish are present. Feed only what is cleared promptly and remove leftovers before they foul the substrate.
Albino Bronze Corys may investigate soft algae and fallen food, but they are not dedicated algae eaters and do not live on scraps or fish waste. Targeted feeding is essential for good body condition. A rounded, well-fed fish should not be confused with an overfed aquarium in which food is left to decay.
Keep at least six Albino Bronze Corys together. In an appropriate group they are usually more confident and show the natural behaviours that make cory catfish appealing: sifting sand, following one another between feeding areas, resting under cover and making short surface dashes. A single fish sold from this listing is one member of the group, not a suitable complete group on its own.
Suitable companions include peaceful community fish with overlapping water and temperature needs, such as many small tetras, rasboras and calm livebearers. Peaceful dwarf cichlids can sometimes work in an aquarium with enough floor space and broken sight lines, but breeding territories must be considered. Avoid fish large enough to swallow them, aggressive or highly territorial bottom-dwellers, and boisterous species that prevent the Corys from feeding. Do not keep them permanently at an unsuitable temperature simply to match a warm-water specialist.
Mature females are generally fuller and broader when viewed from above, while males tend to be slimmer, but young fish are sold unsexed and individual shape varies. Well-conditioned adults may spawn after a change in conditions, often using the characteristic Cory “T-position” before the female places adhesive eggs on aquarium glass, plants or equipment. Adults may eat eggs, so a separate breeding aquarium or moving the eggs is usually needed if raising fry is the goal. Clean water, gentle aeration and very small foods appropriate to the fry are more important than heavy feeding.
Check that barbels remain intact, the belly is not pinched, breathing is steady and every fish joins feeding. Barbel damage is associated with abrasive substrate, accumulated waste and poor hygiene; prevention starts with smooth sand and clean water. Quarantine new livestock where suitable facilities are available, and never expose Corys to an uncycled aquarium.
If illness is suspected, confirm the water parameters first and seek an appropriate diagnosis before medicating. Follow the product label or professional aquatic-veterinary advice rather than combining treatments or increasing doses. Extra aeration is especially important whenever fish show breathing distress.
What you receive: one unsexed Albino Bronze Cory from the selected size option. Order enough fish, or add to a suitable existing group, so its social needs are met. Dispatch size is not adult size, and sex cannot be guaranteed.
Eligible livestock orders are covered by the Tropical Fish Co delivery and Live Arrival Guarantee. Prepare a mature, heated aquarium before ordering. On arrival, inspect the fish and follow the current acclimation instructions supplied with the order. Keep the aquarium lights low while the fish settles, avoid sudden changes in temperature or water chemistry, and monitor breathing, posture, barbels and feeding during the first few days.
The new primary image is a representative illustration of an Albino Bronze Cory. The low-resolution supplier photograph remains later in the gallery as an identity reference and cannot verify the exact individual, shade, sex, size or condition dispatched. The remaining gallery images are representative aquarium illustrations. Albino pigmentation can appear cream, pale gold or pinkish under different lighting, and the fish you receive may not look identical to the gallery.

Love this little Cory. It's quite difficult to see in my tank but it's doing a great job of keeping the bottom of the tank nice and clean.
Healthy and doing well
Received my 6 Albino Corydoras Catfish about 2 weeks ago. They arrived well packaged, in a polystyrene box with foil and newspaper protection. The bag containing the fish was full of air and remained in verry good condition. Delivered by Royal mail. One thing you could add to the package alongside the Fragile sticker is a statement of LIVE FISH as I hope that anyone handling the package would take even more care. They have settled in really well, they are a great fish to watch with their constant search for food! They do a great job of eating any food that gets past my Harlequins and male betta (not a lot LOL) and sinks to the bottom. I also feed them Fluval Bug Bites Bottom Feeder Formula which they love. Bloodworm is another welcome addition as a treat once or twice a week. Overall I would recommend this species as they seem hardy, and are very active, even with the light on in the tank. They are even more active with lights out, and any food fed when the lights go out (my normal routine for bottom feeders) is gone by the morning. Great price on the fish. Good condition on arrival. They are growing daily! ***** 5 Stars!
