Can Longfin Bristlenose Pleco live with Sailfin Molly?
Caution — with care
Why
- Only a narrow pH overlap — keep both around 7.5–7.6.
- No overlapping water hardness: Longfin Bristlenose Pleco wants 6.5–7.5 dGH but Sailfin Molly wants 12–30 dGH.
Sweet spot: both do well at 72–82°F and pH 7.5–7.6 — aim there.
