Ok I have a question.

So I had 2 icthys and it was amazing, they didn’t make anything aggro,but 2 Brontie fell in the water and killed them accidently. So I had to get a new one. It took ages but I eventually tamed one. But as soon as it was tamed 2 megs attacked it. It barely survived, but out when I was taking another icthy with it all the megs and mantas started to attack it. I’m so confused the other ones didn’t make anything aggro
