I've never heard of one attacking a fish, then again I never heard of one attacking a shrimp until someone posted a video of it here. I would say if the fish is unhealthy and dieing already that the snail may come over and eat it, but that would have to be a small fish. I house assassin snails with my fish never had a problem even with cories on the bottom and kuhli loaches hiding in the caves. I've also housed them with my RCS and never had a problem, sure they may of picked a few off here and there but my population was always on the rise so no big deal.
You shouldn't take life to seriously. You'll never get out alive.
