Entity attacks mobs of same type

I want to create a mob that attacks other monsters, but if I set the attack type to Entity Mob, it attacks mobs of the same type aswell.

I tried to use conditions, so that it checks if the mob attacking is the same type and if so, cancel the attack.

It sometimes also doesn't attack at all.
