Good fit for your tank?

Good fit for

  • A roomy peaceful community with ample bottom area
  • A keeper who wants a larger reticulated cory
  • An aquarist comfortable identifying uncommon fish

Think carefully if

  • The aquarium has limited floor space
  • Bottom foods are routinely taken by faster fish
  • The seller cannot distinguish similar patterned corys

Reticulated Corydoras is a peaceful South American callichthyid catfish recognised by a fine dark network pattern over a pale body, usually with a dark dorsal blotch. It should be kept in a same-species group over fine sand in clean, oxygen-rich freshwater.

Appearance and Identification

The pale body is covered by a dark network of lines, usually accompanied by a strong dark blotch in the dorsal fin. Its deep, sturdy build separates it from smaller spotted corys with similar markings.

Identify this profile by the combination of a fine dark network pattern over a pale body, usually with a dark dorsal blotch. Older sources commonly list this fish as Corydoras reticulatus; the current profile follows the accepted or revised placement Brochis reticulata. Colour alone can be unreliable in stressed, juvenile, or poorly conditioned fish, so body shape, snout length, fin pattern, and provenance should also be checked.

Reliable external differences are limited. Mature females generally become larger and noticeably broader through the abdomen, while males remain slimmer, but juveniles are difficult to sex confidently.

Provide a spacious bottom footprint, smooth sand, shaded retreats and open areas for group foraging. Stable water, good oxygenation and regular substrate maintenance are important because food and waste collect in its feeding zone.

Behaviour and Tankmates

This is a peaceful, social and fairly robust bottom dweller. It spends much of its time searching the substrate and becomes more settled when kept with several of its own kind.

Keep at least 6 of the same species or coded population, with 8 or more preferred where space permits. A mixed collection of single corys does not fully replace a proper same-species group.

It is not territorial. Males may briefly chase one another or follow females during courtship, but sustained aggression is unusual when the group has adequate floor space.

It suits communities of peaceful, similarly sized fish that do not monopolise bottom foods. Avoid aggressive cichlids, territorial catfish and cramped tanks where a sturdy group cannot forage comfortably.

Stability importance
Important

Soft to moderately hard, slightly acidic to neutral water is suitable. Provide good oxygenation and keep ammonia and nitrite at zero.

Parameter caveat
Acclimate slowly to changes in temperature, pH, and conductivity. Corydoradine catfish periodically gulp atmospheric air, so the water surface must remain accessible. Warm water holds less oxygen and requires stronger aeration.

Feeding

Diet types
Insectivore, Omnivore, Scavenger
Feeding frequency
Daily
Preferred foods
  • Quality sinking catfish pelletUse a small sinking pellet or wafer as a staple. Feed enough for every fish to reach food after faster midwater fish have eaten.
  • Frozen or live daphnia and cyclopsSmall crustacean prey supports natural foraging and is useful for conditioning breeding groups.
  • Frozen bloodworm, black mosquito larvae, or tubifexOffer clean, appropriately sized portions in rotation rather than as the only food.
  • Soft vegetable-based waferProvides dietary variety, although these catfish are not algae-eating cleanup animals and still require protein-rich food.

Use varied sinking foods, including quality pellets, tablets and frozen or live invertebrate foods. Do not rely on leftovers, and distribute food across the bottom so every fish can feed.

Feed after faster surface and midwater fish have taken their share, and confirm that every individual reaches food. Use small portions once or twice daily, remove persistent leftovers, and vary prepared and frozen or live foods.

Baby foods
  • Newly hatched brine shrimpA primary growth food after fry have absorbed the yolk sac; feed small rinsed portions several times daily.
  • MicrowormsUseful for newly feeding fry that remain close to the substrate.
  • Vinegar eels or cultured infusoriaHelpful for the smallest species and uneven broods during the first feeding stage.
  • Fine powdered fry foodUse sparingly as a supplement and siphon uneaten material to protect water quality.

Breeding follows the familiar cory pattern and has been achieved in aquariums. Well-conditioned adults attach adhesive eggs to glass, plants or spawning material, after which the eggs should be protected because the adults provide no care.
