Can Altum Angelfish live with Phoenix Rasbora?
Not recommended
Why
- Altum Angelfish’s mouth is big enough to swallow Phoenix Rasbora (only 0.8" long) — it will be eaten.
- Almost no shared temperature: Altum Angelfish wants 82–88°F and Phoenix Rasbora wants 75–82°F, so only 82°F suits both — too fine a margin to actually hold.
