Can Altum Angelfish live with Thick-lipped Gourami?
Caution — with care
Why
- Only a narrow temperature overlap — keep both around 82°F.
- Only a narrow pH overlap — keep both around 6.5.
- No overlapping water hardness: Altum Angelfish wants 1–5 dGH but Thick-lipped Gourami wants 6–7.5 dGH.
Sweet spot: both do well at 82–82°F and pH 6.5–6.5 — aim there.
