Here is a few pics of the best fish I have ever owned. The first and last pic is of CK's Bozo & Crusty that I bought at 8 & 9"'s 2-2-2010 from Pet-Co and have grown 2" sense then. The middle pic's of a BK that I bought several weeks later. After keeping a number of fish through the years, I must say that the knives and puffers have my heart strings for now. They are a blast to have the owner of being their keeper.
You have a real beauty. Enjoy the time you have to give him-her. All the best with you Knife!
