Description: The Sand's Cory is a peaceful catfish that is tan with black stripes. These are active little fish that need eat from the bottom of the tank. This is a relatively new species to the aquarium hobby, but has been gaining popularity.

Clean water with low nitrate makes caring for this fish very easy. Besides good water quality, C. davidsandsi's needs include some amount of current and a substrate which is not sharp enough to damage the body or barbels. Cover in the form of plants or nonliving objects is helpful, though there should also be open space for the fish to use. This species of catfish needs to be kept in groups as it is very social- six is a good starting point.

This species is known to hybridize with other Corydoras, most notably C. panda. Viable hybrid davidsandsi young have been produced but they are rarely, if ever seen for sale. To avoid hybridization, it is best for every species of Corydoras in a tank to be kept in large shoals containing both genders.

Breeding Information: Like other Corydoras; water changes can induce spawning (T-clinch). Adding a small powerfilter/powerhead to the tank can help trigger spawning. Eggs are laid on the tank sides, on driftwood, and in plants. Eggs are prone to fungus. Suggest keeping the eggs in a floating net in the tank containing the parent fish. Alternatively, Methylene Blue can be used. Fry are fed with microworms after the yolk sac has been used up (3-4 days).

 

Sexing Information: Females tend to be longer and plumper than males.

 

Diet: Onmivorous - does well with a staple of small pellet food supplimented with freeze dried, frozen or live small catfish foods.

 

Temperment: Peaceful community fish

 

Common Diseases: None specific to species
