Can Clown Pleco live with Green Neon Tetra?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 4–5 dGH.
- Large size gap (Clown Pleco 3.5" vs Green Neon Tetra 1") — the bigger fish may eat the smaller one as they grow.
Sweet spot: both do well at 75–82°F and pH 6–6.5 — aim there.
