Can Tail Spot Pygmy Cory live with Blue Phantom Pleco?
Caution — with care
Why
- Very different sizes (Blue Phantom Pleco 7" 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 dGH.
Sweet spot: both do well at 75–79°F and pH 6.5–7.6 — aim there.
