[edit] Other Scientific Names

Corydoras virescens

[edit] Sexing

Females have a larger underbelly, when viewed from the top will look a lot wider than a male. Males are smaller in length than females also.

[edit] Tank compatibility

A peaceful community fish, will not bother tankmates. Keep with other peaceful community fish.

[edit] Diet

As with most Corydoras, these fish will eat most food which sinks to the bottom of the tank. Sinking algae pellets should be supplemented with flake food or other sinking foods like catfish pellets.

Be aware these fish do have a carnivorous side to them and love foods such as Bloodworm and Brine Shrimp. Vegetable-based foods offer little nutrition to them. They will also eat any dead, dying, or even injured fish, that sit on the substrate too long. They're very opportunistic!

[edit] Feeding regime

These fish are most active at night, so feeding once before lights out is typically enough. Though they can be persuaded to feed during the day.

[edit] Environment Specifics

Requires a sand or small gravel substrate and prefers a planted tank. Keeping a cory on sharp or large gravel can lead to damage to their barbels, which when infected will make it hard for the cory to find food.

Corys are sensitive to salt, as with other scaleless fish, adding salt to the tank will cause them harm.

[edit] Behaviour

• The Corydora group of fish frequently gulps air. This is normal and is not a cause for concern. If too little room is available between the water surface and the hood (<2") the fish may hit the hood. They hold the air in their stomach and the thin lining dissipates the oxygen.
• This fish likes the company of its own kind. It is recommended to keep least 2 or more of the same species. The more you have, the more secure they are and therefore the more you will see them.
• Known to 'blink' its eyes to the amazement of onlookers. The Cory has the ability to tilt its eye down to examine the nearby substrate.

[edit] Identification

Pale in colour with lots of small spots across the whole body and some on the dorsal fin, the belly will appear pinkish.
