Panda cory tank size
Plan for a minimum tank length of 60 cm to provide adequate floor space for the entire group. Seriously Fish lists a smaller 45 cm base length rather than 60 cm. Use the larger floor area to give your fish room to forage together.Plan for a minimum tank length of 24 in to provide adequate floor space for the entire group. Seriously Fish lists a smaller 18 in base length rather than 24 in. Use the larger floor area to give your fish room to forage together.[1]
Fine river sand, wood and shaded resting places suit panda corys, and a planted community layout is also suitable. Keep the substrate clean because dirty bottoms are linked with barbel damage and infections. These fish do not replace regular substrate maintenance.Fine river sand, wood and shaded resting places suit panda corys, and a planted community layout is also suitable.

Panda cory water parameters
Routine captive care guidance is 22–25 °C, pH 6.0–7.4 and 1–12 dGH. Do not use an upper limit of 28 °C as a preferred long-term aquarium temperature.Routine captive care guidance is 72–77 °F, pH 6.0–7.4 and 1–12 dGH. Do not use an upper limit of 82 °F as a preferred long-term aquarium temperature.[1]
The species comes from upper Amazon tributaries in Peru, including streams seasonally cooled by Andean meltwater. This habitat context explains their natural origin, but it is not a recommendation for abrupt aquarium cooling.The species comes from upper Amazon tributaries in Peru, including streams seasonally cooled by Andean meltwater.

Establish biological filtration before introducing fish so that ammonia is undetectable and nitrite is controlled. Clear-looking water does not prove chemical safety. Test ammonia weekly and whenever appetite or behaviour changes, preserve the biological filter, and avoid overfeeding.Establish biological filtration before introducing fish so that ammonia is undetectable and nitrite is controlled.

Feeding panda cories
Use sinking pellets or tablets as staple foods and deliver food to the bottom deliberately. Scraps escaping other fish are not a complete feeding plan. Offer Daphnia, Artemia or bloodworm as live or frozen variety.Use sinking pellets or tablets as staple foods and deliver food to the bottom deliberately.

General RSPCA feeding guidance advises offering two small meals daily, each limited to what the fish actually consume in about two minutes. Adjust portion size to your fish and remove uneaten food to protect water quality.General RSPCA feeding guidance advises offering two small meals daily, each limited to what the fish actually consume in about two minutes.

Typical adult length is 3.5 cm with a maximum adult length of 4.1 cm, whereas Seriously Fish reports 5 cm standard length.Typical adult length is 1.4 in with a maximum adult length of 1.6 in, whereas Seriously Fish reports 2 in standard length.[1]
Most fish sold are farm-bred, and the species is peaceful, but deteriorating water or substrate remains a care concern. Occasional trips to gulp air are normal cory behaviour, but more frequent surfacing with deteriorating conditions calls for checking water quality and oxygenation.Most fish sold are farm-bred, and the species is peaceful, but deteriorating water or substrate remains a care concern.

Breeding panda cories
Use gentle sponge filtration and a varied diet when preparing a breeding group. Females lay adhesive eggs on surfaces such as aquarium glass.Use gentle sponge filtration and a varied diet when preparing a breeding group. Females lay adhesive eggs on surfaces such as aquarium glass.[1]

Panda cory health problems
Ich is a contagious protozoan infection of freshwater fish where white grains on skin or fins, rubbing, mucus or reduced appetite are warning signs. Appearance alone cannot confirm the cause, so reduce introduction risk with at least 30 days of quarantine and separate nets and siphons, and obtain a prompt fish-health diagnosis.Ich is a contagious protozoan infection of freshwater fish where white grains on skin or fins, rubbing, mucus or reduced appetite are warning signs. Appearance alone cannot confirm the cause, so reduce introduction risk with at least 30 days of quarantine and separate nets and siphons, and obtain a prompt fish-health diagnosis.[5]
Bacterial fin rot can cause progressive fin-edge erosion and redness or bloody streaks, with poor conditions and stress favouring infection. Prevent avoidable risk with clean water and protection from injury or harassment, and seek diagnosis rather than assuming all damaged fins have fin rot.Bacterial fin rot can cause progressive fin-edge erosion and redness or bloody streaks, with poor conditions and stress favouring infection.

Ammonia poisoning damages gills and tissues, stresses fish and may cause reduced feeding. It comes from fish metabolism and decaying food or waste, so test water rather than diagnosing by appearance, cycle the filter before stocking and avoid excess feeding.Ammonia poisoning damages gills and tissues, stresses fish and may cause reduced feeding.

Male or female?
Mature females tend to be slightly larger with a rounder abdomen than males, and viewing the fish from above helps you compare them. Immature fish are harder to compare.Mature females tend to be slightly larger with a rounder abdomen than males, and viewing the fish from above helps you compare them.

Why do panda corys swim to the surface?
Occasional trips to gulp air are normal cory behaviour. However, more frequent surfacing under deteriorating conditions calls for checking water quality and dissolved oxygenation.Occasional trips to gulp air are normal cory behaviour. However, more frequent surfacing under deteriorating conditions calls for checking water quality and dissolved oxygenation.[1]
Will panda corys clean the tank?
No, panda corys do not replace substrate maintenance. Dirty bottoms are linked with barbel damage and infections, and you must deliver food directly to the bottom rather than expecting them to live on waste.No, panda corys do not replace substrate maintenance.
