🐡 What is a Pea Puffer?
The Pea Puffer is the smallest freshwater pufferfish in the world, growing to only about 1 inch. Native to India, they live in slow-moving, heavily planted waters and are known for their bold personalities and hunting behavior.
📏 Tank Size & Setup
- Minimum Tank Size: 10 gallons
- Ideal Setup: Heavily planted aquarium
- Flow: Low to moderate
- Substrate: Sand or fine gravel
Pea Puffers thrive in tanks with lots of plants, driftwood, and hiding spots. This helps reduce aggression and creates natural territories.
🌿 Ideal Tank Setup Tips
- Use live plants like Anubias, Java Fern, and Crypts
- Add driftwood and caves for hiding
- Break line-of-sight to reduce aggression
- Keep lighting moderate

Pea Puffers are semi-aggressive and territorial despite their small size. Males can be especially territorial, so proper stocking and tank layout are important.

👥 How Many Pea Puffers Can You Keep?
A good rule:
