Corydoras Catfish
Social bottom-dweller; smooth substrate is preferred.
Planning your aquarium
The library starting point is 20+ US gallons. Plan for the approximate 3-inch adult size and the species' normal activity, not just its current shop size.
The library suggests a group of at least 6. Count every individual when estimating stocking and swimming room.
Mixed-species aquariums may need substantially more space. Tank length, adult behavior, filtration, and hiding spaces all matter.
Tank setup and behavior
- Provide bottom space, suitable substrate, and accessible hiding places.
- Include planting or cover without removing all open swimming space.
Keep a group of compatible corydoras with a smooth, clean substrate that protects their delicate barbels.
Social bottom-dweller; smooth substrate is preferred.
Food and feeding
Food options: Sinking wafers, Small sinking pellets, Frozen bloodworms.
Feed targeted sinking foods after checking that faster tankmates do not eat everything.
Use appropriately sized, complete staple foods and rotate suitable foods for variety. Feed modest portions and remove uneaten food.
Tankmate cautions in the checker
- Use caution with Rainbow Shark: A territorial rainbow shark may chase bottom-dwelling corydoras.
These are selected rule-based cautions, not a complete compatibility assessment.
