Can Wild-Type Betta live with Phoenix Rasbora?
Light caution
Why
- Wild-Type Betta is semi-aggressive — give the peaceful Phoenix Rasbora plenty of space, cover and broken sight lines.
- Large size gap (Wild-Type Betta 2.5" vs Phoenix Rasbora 0.8") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 76–82°F and pH 6–7 — aim there.

How to make it work
- Keep a large, established shrimp colony in a heavily planted tank with moss and cover so enough survive to breed.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
