Stunning in planted tanks
Peaceful community fish
Pygmy Corydoras (Corydoras pygmaeus) are tiny social catfish that regularly swim in the lower-to-mid water column instead of staying only on the substrate. A proper group creates movement throughout the lower half of a planted aquarium.
They remain very small, prefer clean stable water, and do best with smooth substrate and appropriately sized foods.
Care Notes
Feed micro-sized sinking foods and keep the aquarium mature and stable. Pygmy Corydoras often use both the bottom and lower-to-mid water column.
Keep at least 8–10. Larger groups are more confident, visible, and active.
Keep at least 8–10 in a planted 10-gallon or larger aquarium. In our experience, larger groups are much more visible and confident. Feed micro-sized sinking foods rather than assuming they will live on leftovers.

Common Questions
Pygmy Corydoras FAQ
How many Pygmy Corydoras should I keep?+
We recommend at least 8–10. Larger groups are generally more confident and show more natural mid-water schooling behavior.
What substrate do Pygmy Corydoras need?+
Fine sand or another smooth substrate is preferred. Keep the bottom clean and avoid sharp material that can irritate their barbels.
What do Pygmy Corydoras eat?+
Feed micro sinking pellets, frozen daphnia, microworms, and other appropriately sized foods. They should be fed directly rather than relying on leftovers.
Do Pygmy Corydoras stay on the bottom?+
Not all the time. They regularly swim in the lower-to-mid water column, which is one of the traits that makes them unusual among Corydoras.
Are Pygmy Corydoras safe with shrimp?+
Generally compatible with adult shrimp. Very small shrimplets or eggs may still be opportunistically eaten.
How are Pygmy Corydoras shipped?+
Fish ship Monday through Wednesday via Overnight / Next Day Air and typically arrive Tuesday through Thursday.
Live plants give nano fish cover, reduce stress, and create a more natural aquarium. They help break up sightlines, provide shelter for shy fish, and support a healthier planted tank.
