Can Altum Angelfish live with Blue Lobster Crayfish?
Caution — with care
Why
- Blue Lobster Crayfish can grab Altum Angelfish while it sleeps — only fast mid/top-water fish are reasonably safe.
- Only a narrow temperature overlap — keep both around 82°F.
- Only a narrow pH overlap — keep both around 6.5.
- Only a narrow water hardness overlap — keep both around 5 dGH.
Sweet spot: both do well at 82–82°F and pH 6.5–6.5 — aim there.
