Can Altum Angelfish live with Common Pleco?
Caution — with care
Why
- Almost no shared temperature: Altum Angelfish wants 82–88°F and Common Pleco wants 72–82°F, so only 82°F suits both — too fine a margin to actually hold.
- Only a narrow water hardness overlap — keep both around 5–5 dGH.
- Large size gap (Common Pleco 24" vs Altum Angelfish 7") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 82–82°F and pH 6–6.5 — aim there.
