Remarks: Corydoras axelrodi deckeri, also known as Corydoras sp. C3, are a fairly new and uncommon cory catfish from Columbia. They have not been formally described and are currently presumed to be a color form of Corydoras axelrodi. Corydoras deckeri have a whitish silver to tan colored body. They can be identified by their black speckles, mask, and horizontal band on their back and middle. There is some variation in regards to their pattern so it is unlikely that all of the fish you will receive will look the same.
They are active shoalers and will stay near conspecifics, making for a lovely sight. Corydoras feed by searching through sand with their barbels, and sand is necessary for the long-term health of Corys. Gravel substrates tend to be abrasive and damage the barbels, leading to infections and an inability to find food.
Corydoras are often looked at as "scavengers," but they should be treated in a similar fashion as the rest of your fish. They are omnivores and require a mixed diet. Flake food is readily accepted, as is baby brine shrimp and small pieces of blackworm.
