If you check the totk object viewer website, it says tails have a %25 chance of dropping. It feels so much rarer but I started counting my drops and the ratio actually is 1 in 4.

For ice and fire tails I recommend the Gerudo Canyon SkyView Tower. Gerudo desert for electric as well. Electric sucks because they are so spread out compared to ice/fire.

I definitely recommend visiting the totk object viewer if you want to farm legitimately. Otherwise just dupe like others are saying.
