I guess Vodka. Alcohol also works. I know this cause when i was like 5 i had fish and i started out with 13, but each day one would die. I guess whatever one had gave it to all of them. Well there were like 5 left and i was bored so i put alcohol or nailpolish remover in the water, can't remember which and they died right away. Then i felt super bad. I was only 5 lol |
