Can Giant Gourami live with Blue Phantom Pleco?
Light caution
Why
- Giant Gourami is large enough to threaten a small Blue Phantom Pleco — usually fine once both are adult, but watch new additions.
- Only a narrow water hardness overlap — keep both around 5.5–7 dGH.
- Giant Gourami is semi-aggressive — give the peaceful Blue Phantom Pleco plenty of space, cover and broken sight lines.
Sweet spot: both do well at 75–82°F and pH 6.5–7.6 — aim there.

How to make it work
- Target the overlapping water-parameter range and acclimate slowly.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
