⚠ Physiological Mismatch Report

Our stocking engine calculations indicate that putting these two species in the same tank causes acute physiological strain. Below are the calculated parameters that violate safe cohabitation ranges:

Acidity/pH Gap0.2 pH difference

Ghost Shrimp thrives in pH 7-8, while Harlequin Rasbora needs pH 6-6.8.

⚔️ Do Ghost Shrimp and Harlequin Rasbora Fight?

Environmental or structural requirements between these species clash too heavily to allow cohabitation. Water acidity (pH) parameters clash. Harlequin Rasbora prefers a pH of 6-6.8, while Ghost Shrimp requires a pH of 7-8. There is no overlapping safe pH range.

🍽️ Swimming Layers & Feeding Competition

To satisfy their dietary requirements, offer a varied feeding schedule. Sinking pellets or wafers are ideal for bottom dwellers, while floating flakes or micro-granules support mid and top dwellers. The Ghost Shrimp occupies the bottom layer, while the Harlequin Rasbora occupies the mid layer. This separation of swimming zones naturally minimizes direct interactions and reduces competition during feeding times.

📏 Size Difference & Predation Threat

Both species are closely matched in physical dimensions, with Ghost Shrimp growing to 1.5 inches and Harlequin Rasbora reaching 1.8 inches. This size balance ensures neither species holds a physical dominance advantage.
