Can you keep Corydoras Catfish and Pea Puffer together?
Algorithmically generated environmental and behavioral compatibility report.
Algorithmic Assessment
Aggression incompatibility. Pea Puffer is an aggressive/territorial species. Peaceful or community fish like Corydoras Catfish cannot be housed with highly territorial fish safely.

⚠ Physiological Mismatch Report
Our stocking engine calculations indicate that putting these two species in the same tank causes acute physiological strain. Below are the calculated parameters that violate safe cohabitation ranges:
⚔️ Do Corydoras Catfish and Pea Puffer Fight?
Behavioral analysis indicates a severe compatibility clash. The Pea Puffer is known for highly territorial and aggressive behaviors. In a shared environment, it is highly likely to harass, injure, or stress the more peaceful Corydoras Catfish, making them completely incompatible cohabitants.
🍽️ Swimming Layers & Feeding Competition
To satisfy their dietary requirements, offer a varied feeding schedule. Sinking pellets or wafers are ideal for bottom dwellers, while floating flakes or micro-granules support mid and top dwellers. The Corydoras Catfish occupies the bottom layer, while the Pea Puffer occupies the mid layer. This separation of swimming zones naturally minimizes direct interactions and reduces competition during feeding times.
📏 Size Difference & Predation Threat
There is a moderate size difference. The Corydoras Catfish (2.5 inches) is noticeably larger than the Pea Puffer (1.0 inches). While not an immediate predation threat under normal circumstances, ensure the smaller specimens are not small enough to be eaten and have plenty of shelter.

Frequently Asked Questions: Corydoras Catfish & Pea Puffer Compatibility
Are Corydoras Catfish and Pea Puffer good tank mates?
Aggression incompatibility. Pea Puffer is an aggressive/territorial species. Peaceful or community fish like Corydoras Catfish cannot be housed with highly territorial fish safely.
Can you put Corydoras Catfish and Pea Puffer in the same tank together?
Behavioral analysis indicates a severe compatibility clash. The Pea Puffer is known for highly territorial and aggressive behaviors. In a shared environment, it is highly likely to harass, injure, or stress the more peaceful Corydoras Catfish, making them completely incompatible cohabitants.
What water temperature and pH parameters do Corydoras Catfish and Pea Puffer need?
Both species require compatible parameters. Corydoras Catfish needs a temperature of 72°F to 78°F and a pH of 6.5 to 7.5. Meanwhile, Pea Puffer needs a temperature of 74°F to 82°F and a pH of 6.5 to 7.5. Shared overlap range: 74°F–78°F temperature and 6.5–7.5 pH overlap.
What is the minimum combined tank volume required to house Corydoras Catfish and Pea Puffer?
To successfully house both species together, a baseline of 10 gallons is required. However, because the setup includes territorial behavior from Pea Puffer (aggressive), we recommend an adjusted minimum tank volume of at least 30 gallons (adding a 20-gallon safety buffer) to establish separate visual boundaries and minimize stress.
