Can Green Neon Tetra live with Gold Kuhli Loach?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 3–5 dGH.
- Large size gap (Gold Kuhli Loach 3.5" vs Green Neon Tetra 1") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 75–84°F and pH 5.5–6.5 — aim there.
