Can Neon Tetra live with King Tiger Pleco?
Caution — with care
Why
- No overlapping temperature: Neon Tetra wants 68–78°F but King Tiger Pleco wants 79–86°F.
- Only a narrow water hardness overlap — keep both around 5.5–7 dGH.
- Large size gap (Neon Tetra 1.5" vs King Tiger Pleco 6") — the bigger fish may eat the smaller one as they grow.
