Peppered cory tank size
Furnish the aquarium with fine sand, adding pieces of bogwood or smooth stones to create sheltered resting spots while retaining unobstructed feeding zones. The entire bottom crew requires ample surface area across the floor, where they sift through soft sediments hunting for edible items.Furnish the aquarium with fine sand, adding pieces of bogwood or smooth stones to create sheltered resting spots while retaining unobstructed feeding zones.

Keep open vertical lanes extending straight up to the water surface. These catfish possess a specialised intestinal tract capable of extracting atmospheric oxygen, meaning they need free access to gulp air whenever necessary.Keep open vertical lanes extending straight up to the water surface.

Peppered cory water parameters
Target a temperature between 22–26 °C, maintain acidity between pH 6.0–7.0, and aim for a general hardness of 1–12 dGH.Target a temperature between 72–79 °F, maintain acidity between pH 6.0–7.0, and aim for a general hardness of 1–12 dGH.[1]
Ammonia represents an acute danger to fish and must remain undetectable at all times. Because decomposing food particles and biological waste release this toxin, support a mature biological filter and avoid overfeeding. Never assume visual clarity equates to safe water; run test kits whenever behaviour alters or fish show declining appetites.Ammonia represents an acute danger to fish and must remain undetectable at all times.

Feeding Peppered cories
Offer quality sinking pellets or tablets paired with live or frozen daphnia and bloodworm, alongside standard flakes. Providing varied foodstuffs meets the dietary recommendations for this species.Offer quality sinking pellets or tablets paired with live or frozen daphnia and bloodworm, alongside standard flakes.

Administer meals twice daily in modest amounts cleared within approximately two minutes. Watch bottom foragers consume their ration directly on the floor and modify the quantity according to their actual intake. Never depend on these catfish to scavenge waste or subsist on leftovers from other species; deliver dedicated sinking items directly down to the group.Administer meals twice daily in modest amounts cleared within approximately two minutes.

The maximum adult standard length reaches 7 cm. Beyond regional differences in body markings and hues observed across wild habitats, an albino variety also exists.The maximum adult standard length reaches 3 in. Beyond regional differences in body markings and hues observed across wild habitats, an albino variety also exists.[1][13]
Occasional dashes up to the surface represent routine intestinal respiration, though chronic distress trips call for thorough water testing and tank evaluation. Exercise caution when moving or catching these fish, as their leading pectoral rays carry stiff defensive spines.Occasional dashes up to the surface represent routine intestinal respiration, though chronic distress trips call for thorough water testing and tank evaluation.

Peppered cory health problems
Because this parasite can lodge inside gill tissue without producing noticeable external dots, obtain a careful diagnosis rather than treating every white blemish as white spot.Because this parasite can lodge inside gill tissue without producing noticeable external dots, obtain a careful diagnosis rather than treating every white blemish as white spot.[5]
Isolate incoming stock in a separate quarantine tank for at least 30 days and refrain from sharing damp nets or equipment across different aquariums to lower the likelihood of introducing ich.Isolate incoming stock in a separate quarantine tank for at least 30 days and refrain from sharing damp nets or equipment across different aquariums to lower the likelihood of introducing ich.[5]
Degraded environmental conditions elevate infection hazards, so uphold good water hygiene and remove causes of physical conflict. Never treat an isolated torn fin ray as an immediate bacterial diagnosis.Degraded environmental conditions elevate infection hazards, so uphold good water hygiene and remove causes of physical conflict. Never treat an isolated torn fin ray as an immediate bacterial diagnosis.[4]
Cotton-wool fungal issues produce pale, tufted patches on traumatised flesh, typically appearing following physical wounds, rough netting, or poor environmental quality. Minimise infection hazards by removing sharp hardscape, handling specimens gently, and keeping water clean, verifying diagnoses because mouth rot can mimic fungal growth.Cotton-wool fungal issues produce pale, tufted patches on traumatised flesh, typically appearing following physical wounds, rough netting, or poor environmental quality.

Male or female?
Mature females develop a significantly larger, broader, and rounder body profile than males, a physical contrast that turns particularly evident when females fill with eggs.Mature females develop a significantly larger, broader, and rounder body profile than males, a physical contrast that turns particularly evident when females fill with eggs.[1]
Questions
How big do paleatus Corydoras get?
Specimens grow to an adult length of 7 cm standard length. Fully grown females attain a broader, rounder form and reach a larger overall size than males, especially when gravidity occurs.Specimens grow to an adult length of 3 in standard length. Fully grown females attain a broader, rounder form and reach a larger overall size than males, especially when gravidity occurs.[1]
How many corys should you keep together?
House at least six individuals together. They represent a peaceful, social catfish that demands company of their own kind alongside ample floor room to sift through sandy substrate collaboratively.House at least six individuals together. They represent a peaceful, social catfish that demands company of their own kind alongside ample floor room to sift through sandy substrate collaboratively.[1][13]
Do Corydoras keep your tank clean?
No, never rely on these fish to tidy your tank or subsist on leftover scraps. Leftover food and biological waste produce dangerous ammonia, requiring dedicated feeding of sinking items and a properly maintained biological filter.No, never rely on these fish to tidy your tank or subsist on leftover scraps. Leftover food and biological waste produce dangerous ammonia, requiring dedicated feeding of sinking items and a properly maintained biological filter.[1][3]
How many times should I feed my Corydoras?
Provide two modest feedings daily that disappear in around two minutes. Observe the substrate directly to ensure sinking tablets and pellets arrive at the bottom instead of being intercepted by midwater swimmers.Provide two modest feedings daily that disappear in around two minutes. Observe the substrate directly to ensure sinking tablets and pellets arrive at the bottom instead of being intercepted by midwater swimmers.[2][1]
Do Corydoras prefer sand or gravel?
Provide a sandy floor. These bottom dwellers constantly sift through soft sand while searching for nourishment, so arrange fine substrate with wood or stones to combine open feeding areas with protective cover.Provide a sandy floor.
