Can Phoenix Rasbora live with Colombian Zebra Pleco?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Large size gap (Phoenix Rasbora 0.8" vs Colombian Zebra Pleco 3.5") — the bigger fish may eat the smaller one as they grow.
Sweet spot: both do well at 77–82°F and pH 6.5–7 — aim there.
