Can Gold Gourami live with Red-Line Rasbora?
Light caution
Why
- Gold Gourami is semi-aggressive — give the peaceful Red-Line Rasbora plenty of space, cover and broken sight lines.
- Large size gap (Gold Gourami 6" vs Red-Line Rasbora 1.75") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 73–81°F and pH 6–7 — aim there.
