a month ago i drained my pond to net out my knives, my gar, and my pike. i pulled out everything but my clown knife i thought it had died. i left my pacu in until now and i drained my pond again to pull out the pacu, when the water level got below the lip of the pot holding some of my lilly pad roots low and behold my clown knife laying there. i took a look at the thermometer and my water temp was 61 degrees. this has got to be a record or something, or are these guys just that hardy? pics to come once he adjusts to the 55.
