Can Lambchop Rasbora live with Swordtail?
Not recommended
Why
- Swordtail’s mouth is big enough to swallow Lambchop Rasbora (only 1.25" long) — it will be eaten.
- Only a narrow pH overlap — keep both around 7.
- No overlapping water hardness: Lambchop Rasbora wants 2–10 dGH but Swordtail wants 12–30 dGH.
