When you're done trying to knock out tame a dino, DO NOT LET IT GO IN THE WATER. I was once taming a thorny dragon in the water ( I know it's dumb he could die) but once I was ALMOST DONE, a piranha came with it's friends and ate him up. So I repeat, DO NOT LET ANY DINO YOURE TRYING TO TAME GO IN THE WATER.
These piranhas are SOOOO annoying!One time I was passive taming and Equus and it ran into the water, Then about 2-4 piranhas came up and killed my Equus! I was so sad and I went and killed them. WildCard, If you see this lower the percentage of piranhas. Thank You!
