Can Green Neon Tetra live with Gold Kuhli Loach?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 3–5 dGH.
- Large size gap (Green Neon Tetra 1" vs Gold Kuhli Loach 3.5") — the bigger fish may eat the smaller one as they grow.
Sweet spot: both do well at 75–84°F and pH 5.5–6.5 — aim there.
