Tank Mate Guide

Best Tank Mates for Opaline Gourami

Opaline Gouramis need tank mates that match their 73-82F temperature range, pH 6-8, adult size, and semi-aggressive temperament. Opaline Gouramis use the upper water column and appreciate floating plants. Avoid cramped tanks with multiple territorial surface fish.

Tank Setup Tips

Start with at least 30 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.
