I've currently not wanted an Angler due to to their only use being for the gel that let's us Tame Cndinarias, but I know how to. First, go very, very deep into the ocean(Like, Mosa deep.), and look around for a blinding light. Turn up the gamma if you must, and you'll likely find an Angler to tame. Use Shock Darts, maybe a a Dunkylo to get you down there and protect you, and watch out for Mosasauruses or Eurptyds. You might also find the Squid down there, but I forgot it's name. Anglers aren't nessacerily a better tame in the game, but if you want, that's how you do it!
