Can King Tiger Pleco live with Flash Pleco (L204)?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 6–7 dGH.
- Large size gap (King Tiger Pleco 6" vs Flash Pleco (L204) 20") — the bigger fish may eat the smaller one as they grow.
Sweet spot: both do well at 79–82°F and pH 6.5–7.6 — aim there.
