Can Brazos Dwarf Crayfish live with Tail Spot Pygmy Cory?
Caution — with care
Why
- Brazos Dwarf Crayfish hunts along the bottom and will catch the bottom-dwelling Tail Spot Pygmy Cory, especially at night.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
Sweet spot: both do well at 72–75°F and pH 6.5–7.6 — aim there.
