Tank Mate Guide

Best Tank Mates for Pea Puffer

Pea Puffers need tank mates that match their 75-82F temperature range, pH 6.8-7.8, adult size, and aggressive temperament. Pea puffers are small but nippy and predatory. Most community fish, shrimp, and snails are poor tank mates unless the setup is species-only or heavily managed.

Tank Setup Tips

Start with at least 10 gallons, keep water stable, and stock schooling species in proper groups. If the tank mate list includes caution species, add more plants, caves, and open swimming room before introducing them.

For a specific pair, use the compatibility checker or visit generated pair pages from the cards above. Compatibility is strongest when the aquarium is mature and each species can eat without being chased.
