What are some things you could add to a fish tank to kill the fish inside?

Toxic chemicals, such as ammonia or chlorine, can be poisonous to fish; too much salt added to the water can be damaging; objects like plastic bags, twigs, and leaves could fill up the tank and damage the fish's gills; heating equipment could cause the water to overheat; and some types of decorations, such as rocks and statues, could cause the fish to hurt themselves. Additionally, certain additives, such as algae growth stimulators, can be hazardous.
