So I was down with a fever for a couple days but just before that I put in a beautiful piece of wood to make my tank pretty, in doing so I must have knocked the thermostat out of the tank and over the couple days I was out of commission and didn’t worry about my tank, it went up to 120° so I literally cooked my fish...... what now? I mean I know to get all the fish death out but how much of a functional ecosystem do I need to disrupt
