My Porcupine Puffer along with 3 other fish died abruptly today. The puffer has been dead for a maximum of 12 hours. But also could’ve died only 2 hours ago. I just got home. I don’t know if porcupines release a toxin upon death or after 12 hours of being dead. My main concern is, I have open wounds on my hand. Will I be safe putting my hand in the water? All I’m worried about is if the puffer releases toxin. I’m not worried about a dirty fish tank.
