How do you properly tame an ichthyovenator?
A 150 ichthyovenator spawned on the beach just up wind from my base, so I knocked her out and shoved some fish in her inventory, but the taming process doesn't seem to be going well. For starters it is taming extremely slowly, prime fish meat only gives it like four percent per bite, which isn't too big of a deal, but the taming effectiveness makes me think I'm doing something wrong. Whenever it eats regular fish meat it loses damn near an entire percent of the taming effectiveness, I put regular meat in there thinking it was coded like a regular carnivore, but it didn't even register that as a taming food, so is it meant to be this brutal or am I just doing something wrong? I'd use kibble if I had some but I'm not at that point yet, and I also don't want to leave it for later because I've had other high level creatures wander off and vanish, there was even another icthyo that I wanted to tame before this one that dove underwater and hasn't been seen since
