Can Discus live with Fancy Guppy (Female trio)?
Caution — with care
Why
- Only a narrow temperature overlap — keep both around 82°F.
- Only a narrow pH overlap — keep both around 6.8–7.
- Only a narrow water hardness overlap — keep both around 8 dGH.
- Discus is large enough to threaten a small Fancy Guppy (Female trio) — usually fine once both are adult, but watch new additions.
Sweet spot: both do well at 82–82°F and pH 6.8–7 — aim there.
