So I didn't complete the tame because it wasn't a high enough level. I built a trap that has windows on the side and after I trapped it, I was able to look it right in the mouth, through the window, ready to feed black pearls. It did slap me once through the window, but wasn't able to grab me. Going to try again when I trap a higher level and hopefully this will be effective without the need for losing any tames to it's grip.
