Can Common Pleco live with Tail Spot Pygmy Cory?
Caution — with care
Why
- Very different sizes (Common Pleco 24" vs Tail Spot Pygmy Cory 1") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
Sweet spot: both do well at 72–79°F and pH 6.5–7.6 — aim there.
