Can Altum Angelfish live with Platy?
Caution — with care
Why
- Almost no shared temperature: Altum Angelfish wants 82–88°F and Platy wants 70–82°F, so only 82°F suits both — too fine a margin to actually hold.
- No overlapping pH: Altum Angelfish wants 4.5–6.5 but Platy wants 7–8.2.
- No overlapping water hardness: Altum Angelfish wants 1–5 dGH but Platy wants 10–28 dGH.
- Altum Angelfish is large enough to threaten a small Platy — usually fine once both are adult, but watch new additions.
