Can Black Skirt Tetra live with Tail Spot Pygmy Cory?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Black Skirt Tetra is semi-aggressive — give the peaceful Tail Spot Pygmy Cory plenty of space, cover and broken sight lines.
Sweet spot: both do well at 72–79°F and pH 6.5–7.5 — aim there.
