In school we had a 'Piranha' named Chomper who really was a pacu that was bought mislabeled as a piranah. He lived in a 5 gallon tank
and was fed a sole diet of rosy-red minnows. To top that off the tank was totally bare with minimum filtration and when I tried to explain to the teacher that this was not a piranha they totally ignored me!!! The thing didn't even have teeth!! I felt horrible for the poor fish....
About a week ago the fish mysteriously disappeared along with the tank and if you think the 5gallon part was bad...here's worse...
Someone (a student) had apparently dumped DISH SOAP INTO THE TANK as a joke!!! Now the pacu is dead and he didn't even have a decent life...
I wish I would have caught this sooner. Just goes to show how IRRISPONSIBLE some people are and I can't believe someone would actually poison the fish. 
Ugh I just needed to rant!
