Choosing Betta Fish Tank Mates
Good Betta Fish tank mates share the same temperature and pH window, will not be eaten by (or eat) the Betta Fish, and do not compete for the same swimming zone or feeding time. Each pair guide below scores those factors from 0 to 100 and gives the minimum tank size for keeping both species together.
Start with the highest-scoring pairs; anything under 45 is listed so you know what to avoid, not as a recommendation.

Betta & Shrimp
Compare the most common shrimp tank-mate options. Amano shrimp are usually the more robust choice; cherry and ghost shrimp remain individual-temperament risks.
