Can Leopard Frog Pleco live with Swordtail?
Caution — with care
Why
- No overlapping water hardness: Leopard Frog Pleco wants 6–7.5 dGH but Swordtail wants 12–30 dGH.
- Swordtail is semi-aggressive — give the peaceful Leopard Frog Pleco plenty of space, cover and broken sight lines.
Sweet spot: both do well at 77–82°F and pH 7–7.6 — 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.
