Can Common Pleco live with Siamese Algae Eater?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Large size gap (Common Pleco 24" vs Siamese Algae Eater 6") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 72–79°F and pH 6.5–7.6 — aim there.
