Can Thai Devil Crab live with Kuhli Loach?
Not recommended
Why
- Thai Devil Crab hunts along the bottom and will catch the bottom-dwelling Kuhli Loach, especially at night.
- No overlapping pH: Thai Devil Crab wants 7.5–8.5 but Kuhli Loach wants 5.5–7.
- Only a narrow water hardness overlap — keep both around 8–10 dGH.
