Can Black Sail Cory live with Gold Gourami?
Light caution
Why
- Gold Gourami is semi-aggressive — give the peaceful Black Sail Cory plenty of space, cover and broken sight lines.
- Large size gap (Gold Gourami 6" vs Black Sail Cory 2") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 75–82°F and pH 6–7 — aim there.
