Tip : DO NOT bring these guys to waters with Cnidarias (jellyfish).

they will not survive because of their low HP pool (you can level up their health but it wont help much)

and always avoid waters with Cnidarias because their detection range is just broken.

by the way, this is how i lost my Sarco, Swampy Bob.

R.I.P

i also started a new save, deleted the previous one (i felt helpless) and tried to not repeat the same mistakes. (im still gonna tame a sarco in my new save)
