We figured out that he is 16 years old because my sister-in-law matched it to an event in her life that happened in 1982...she had him first and then couldn't keep him. My partner thought he was about 12 or 13 and I thought that was pushing it, so when we learned this we were pretty blown away. It actually freaks me out quite a bit because I am scared of losing him, but he is healthy and pushy and his skin looks good, no damage or funny marks.
I haven't been far into this site before and was really pleasantly surprised today when I found all these Ghost Knife threads. It's awesome. No one could have told me two years ago that I would turn into a fish freak.
There is a picture of the Ghost Knife in my gallery that is maybe a year old. My TSN's picture is there too...he's about two or three years old and for me he is another mind blower.
