So I came home tonight and went to check on the tanks like I usually do. Tonight though I noticed something on its side in the 700 gallon so I fished it out. It was one of my 19 inch clown knifes that I have had for a long time. Im not really sure why it died. I noticed that it hasn't been eating as much lately but didn't really show any signs of stress. He always hung out with the other clown knife and they kinda stuck together. Im pretty bummed that it decided to go cause I think those fish are some of the coolest around. i stuck it in the freezer for now because I wanted to get a picture of it but couldn't find the camera. Ill get some tomorrow of it against the tape measure.
