I used to have a JD. It was cool. Had awsome color, but I had to get rid of him. He was such a bully in the beginning. He totally beat the crap out of my Oscar and Royal Clown Knife. The Oscar grew bigger and he stopped punking him. They actually started teaming up on the Knife. The Knife died. Then I put in a Jag that was half it's size...the Jag soon took over and punked the JD. Eventually, the Oscar started to punk the JD (probably paying him back for the first month of his life in my tank). I eventually had to get rid of the JD for his own safety. Then the Oscar had to go. It was just the Jag, a Clown Knife (got another one) and some Catfish. The Clown got totaaly hammered by the Jag, but now I'm on a different fish. So I'll end my story now.
