Hi..tons of things:
1) putting fish in an uncycled tank and exposing them to ammonia
2) infrequent water changes (high nitrates)
3) rapid swings in tank temps
4) putting aggressive fish in a community tank

just to name a few...........SH

Sneaking up on fish when they're looking the other way scares the crap out of them when they realize you're there.
