Can Noble Gourami live with Royal Pleco?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 6–7 dGH.
- Large size gap (Noble Gourami 3" vs Royal Pleco 17") — the bigger fish may eat the smaller one as they grow.
Sweet spot: both do well at 73–75°F and pH 6.5–7.5 — aim there.
