Can Dwarf Emerald Rasbora (nanus) live with Zebra Pleco?
Caution — with care
Why
- Almost no shared temperature: Dwarf Emerald Rasbora (nanus) wants 72–79°F and Zebra Pleco wants 79–86°F, so only 79°F suits both — too fine a margin to actually hold.
- Very different sizes (Zebra Pleco 3.5" vs Dwarf Emerald Rasbora (nanus) 0.7") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Only a narrow water hardness overlap — keep both around 5–6 dGH.
Sweet spot: both do well at 79–79°F and pH 6.5–7.5 — aim there.
