OMG I too once had a murderous Molly fish. Killed any other fish put in the tank with him. Then when he got moved to his own smaller time out tank, tried to commit suicide not once, not twice, but three times, by jumping out and drying up. Each time, he was found farther and farther from his bowl, and each time, he survived. Badass killer fish. LOOOOOOL
