Can Black Molly live with Axelrod's Rasbora?
Caution — with care
Why
- No overlapping pH: Black Molly wants 7–8.5 but Axelrod's Rasbora wants 4–6.5.
- No overlapping water hardness: Black Molly wants 12–30 dGH but Axelrod's Rasbora wants 1–6 dGH.
- Very different sizes (Black Molly 4" vs Axelrod's Rasbora 0.6") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
