Can Ember Tetra live with Yucatan Molly?
Caution — with care
Why
- No overlapping pH: Ember Tetra wants 5.5–7 but Yucatan Molly wants 7.5–8.5.
- No overlapping water hardness: Ember Tetra wants 1–8 dGH but Yucatan Molly wants 15–30 dGH.
- Very different sizes (Yucatan Molly 6" vs Ember Tetra 0.8") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
