Can Neon Green Rasbora live with Swordtail?
Caution — with care
Why
- No overlapping water hardness: Neon Green Rasbora wants 2–10 dGH but Swordtail wants 12–30 dGH.
- Very different sizes (Swordtail 5.5" vs Neon Green Rasbora 0.8") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Swordtail is semi-aggressive — give the peaceful Neon Green Rasbora 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.
