Can Two-Saddled Cory live with Swordtail?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 12–12 dGH.
- Swordtail is semi-aggressive — give the peaceful Two-Saddled Cory plenty of space, cover and broken sight lines.
Sweet spot: both do well at 72–79°F and pH 7–7.5 — aim there.

How to make it work
- Target the overlapping water-parameter range and acclimate slowly.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
