1. Potential for Disease Transmission: Garra Rufa is a known carrier of several diseases and parasites that can significantly affect native Australian fish species. These diseases may not be present in Australia and pose a significant threat if introduced.
2. Environmental Impact: Garra Rufa exhibits a unique feeding behavior in natural environments by grazing on skin and feeding on ectoparasites. Concerns have been raised regarding its potential impact on Australia's native aquatic organisms and ecosystems if it were to establish itself in waterways.
3. Genetic Contamination: Introducing Garra Rufa could lead to genetic contamination of closely related native species through hybridization. This can have long-term detrimental consequences for native populations.
Therefore, the importation of Garra Rufa is prohibited in Australia, and strict penalties apply for attempting to bring live specimens into the country.
