Not to hard to tame, they like to stay near the surface and they usually spawn more in the northern part of the island. Prime meat is the best to use, and remember it’s a passive tame and it won’t aggrieved unless you it but watch for mantas which will follow the basilo and attack you when you feed it, after the first feed it takes a couple minutes to feed again but after the second one, it only takes around 10 seconds for each feed.
