Reports that killer piranhas were found in Diyawanna Oya were unfounded experts and environmentalists said yesterday, stressing that they had not come across a single one in thelocal water bodies. There may be different species like Paccu or Dollar Fish, they added
One expert stressed that piranhas could not survive in the Diyawanna Oya as it was polluted.
Naturalist/Researcher Kelum Manamendra-arachchi said that he had neither heard nor come across piranha in local water bodies.
He said that species of piranha such as the red bellied piranha (Serrasalmus nattereri), the spotted piranha (Serrasalmus spilopleura) and the white piranha (Serrasalmus rhombeus) could adapt to water found anywhere.
Among those species, the spotted piranha and the abominable red bellied piranha would breed progressively in most types of fresh waters. Of the three species, the red bellied piranha and the white piranha pose a threat to humans, but mostly they were an invasive threat, he said.
