General Rules
- 1. Never put 2 male bettas together
- 2. Colorful fish (male guppies) trigger betta aggression
- 3. Bottom dwellers (corydoras, plecos) are safest betta mates
- 4. Flowerhorns should be kept alone — too aggressive for community
- 5. Always use a tank larger than the minimum — more space = less fighting
