Can Moonlight Gourami live with Guppy?
Caution — with care
Why
- No overlapping water hardness: Moonlight Gourami wants 6–7.5 dGH but Guppy wants 8–20 dGH.
- Large size gap (Moonlight Gourami 6" vs Guppy 2") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 77–82°F and pH 6.8–7.6 — aim there.
Side-by-side
