Hey, if you want an easy way to get rid of these things one way is to get a Sarco because piranhas swim away and you don’t even need to be riding the Sarco for the piranhas to leave you alone. Another way to get rid of piranhas is having a high-level. T-Rex it kills the piranhas in two bites. Another tip don’t use short range weapons instead use long rage, weapons, like bow and arrows, crossbows and spears.
