Can Moonlight Gourami live with Red-Line Rasbora?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Large size gap (Moonlight Gourami 6" vs Red-Line Rasbora 1.75") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 77–81°F and pH 6.5–7 — aim there.
