"In a recent landmark decision, a New York appeals court upheld the cruelty conviction and sentencing of a fish killer to two years in prison. The court decision is worth noting, as it points to a growing awareness of the intelligence of these animals and the importance they have in some people's lives." this is a real case from 2003 so it is very well possible to report this to the authorities, deliberate destruction of ones tank with bleach would qualify.
