Can Emerald Dwarf Rasbora live with Pearl Gourami?
Caution — with care
Why
- Almost no shared temperature: Emerald Dwarf Rasbora wants 68–77°F and Pearl Gourami wants 77–82°F, so only 77°F suits both — too fine a margin to actually hold.
- Very different sizes (Pearl Gourami 4.5" vs Emerald Dwarf Rasbora 0.9") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
Sweet spot: both do well at 77–77°F and pH 7–7.5 — aim there.
