Can Betta (Siamese Fighting Fish) live with Dwarf Cory (Habrosus)?
Caution — with care
Why
- Betta (Siamese Fighting Fish) is semi-aggressive and may bully the peaceful Dwarf Cory (Habrosus) — give lots of space and cover.
- Betta (Siamese Fighting Fish) is large enough to threaten a small Dwarf Cory (Habrosus) — usually fine once both are adult, but watch new additions.
Sweet spot: both do well at 76–79°F and pH 6–7.5 — aim there.

How to make it work

- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
