Can Pitbull Pleco live with Sailfin Molly?
Caution — with care
Why
- Only a narrow pH overlap — keep both around 7.5.
- Only a narrow water hardness overlap — keep both around 12 dGH.
- Sailfin Molly is large enough to threaten a small Pitbull Pleco — usually fine once both are adult, but watch new additions.
Sweet spot: both do well at 72–79°F and pH 7.5–7.5 — aim there.
