Can Royal Pleco live with Three Spot / Blue Gourami?
Caution — with care
Why
- Three Spot / Blue Gourami is semi-aggressive and may bully the peaceful Royal Pleco — give lots of space and cover.
- Large size gap (Royal Pleco 17" vs Three Spot / Blue Gourami 5") — the bigger fish may eat the smaller one as they grow.
Sweet spot: both do well at 73–82°F and pH 6.5–7.5 — aim there.
