Can Altum Angelfish live with Fire Rasbora?
Caution — with care
Why
- Altum Angelfish may eat Fire Rasbora; add only full-grown adults, because juveniles and fry will be picked off.
- No overlapping temperature: Altum Angelfish wants 82–88°F but Fire Rasbora wants 72–79°F.
- Only a narrow water hardness overlap — keep both around 4–5 dGH.
