Pea Puffer

Planning your aquarium

The library starting point is 10+ US gallons. Plan for the approximate 1-inch adult size and the species' normal activity, not just its current shop size.

The minimum group count is not a compatibility recommendation; assess temperament, sex, territory, and tankmates.

Mixed-species aquariums may need substantially more space. Tank length, adult behavior, filtration, and hiding spaces all matter.

Tank setup and behavior

• Maintain stable, species-appropriate water and provide a mix of cover and swimming room.

Tiny predatory puffer with complex social behavior; often best planned as a species-focused setup.

Food and feeding

Food options: Frozen bloodworms, Small snails, Live or frozen crustaceans.

Use appropriately sized, complete staple foods and rotate suitable foods for variety. Feed modest portions and remove uneaten food.

Tankmate cautions in the checker

• Avoid or investigate Cherry Shrimp: Pea puffers are active micro-predators and commonly hunt dwarf shrimp.
• Avoid or investigate Blue Dream Shrimp: Pea puffers are likely to hunt dwarf shrimp.
• Avoid or investigate Ramshorn Snail: Pea puffers commonly hunt small snails.
• Avoid or investigate Bladder Snail: Bladder snails are common prey for pea puffers.
• Use caution with Olive Nerite Snail: Puffers may bite snails; nerite size does not guarantee safety.
• Use caution with Zebra Nerite Snail: Puffers may bite the snail or harass exposed soft tissue.

These are selected rule-based cautions, not a complete compatibility assessment.
