Rampage Caridina Variant
The Rampage variant, developed by renowned breeder Yang Zhenhua (HWA Shrimp), represents a pivotal moment in the evolution of ornamental shrimp breeding. First introduced in 2014, this groundbreaking lineage laid the foundation for today’s popular Fancy Tiger and Lava Tiger varieties. While no longer in existence in its pure form, the Rampage’s legacy continues to influence modern shrimp breeding, making it a subject of great interest for enthusiasts and collectors alike.

History
Development began in 2008 when Hwa Shrimp started crossing Caridina cantonensis (Crystal Red Shrimp and Crystal Black Shrimp) with wild Caridina mariae (Tiger Shrimp). Through experimentation, Hwa discovered that only caridina mariae females would successfully breed with male Crystal Red Shrimp. Female Crystal Red Shrimp did not breed with caridina mariae males.
The resulting offspring underwent extensive backcrossing (line breeding) to refine traits such as coloration and stripe patterns. This process, while producing the desired aesthetic, resulted in a genetically weakened lineage.
Officially introduced in 2014 as the “Rampage Variant,” these shrimp were the precursors to today’s Fancy Tigers. The Rampage lineage later contributed to the development of the renowned Lava Tiger shrimp.
