I was a kid and real pissed i had no idea what i was doing had a 75 or 55 stocked with all sorts of fish. Petland had some snakeheads and i had no clue what they were all about. Man they hit the 10 or 11 inch mark and went bananas. Killed everything. I just threw them in the front yard a few days later my mom was screaming the she saw snakes in the yard lol...they ended up in the sewer afterwards
