Can Common Pleco live with Opaline Gourami?
Light caution
Why
- Opaline Gourami is semi-aggressive — give the peaceful Common Pleco plenty of space, cover and broken sight lines.
- Large size gap (Common Pleco 24" vs Opaline Gourami 6") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 72–82°F and pH 6–8 — aim there.
