heehee. That's Joker. He's always been deformed like that. In fact, thats how we got him. The LFS gave him to us when he was about 2 inches. I know I have had a few comments that he should have been culled but, I don't see why. He eats great, has a awesome personality, is growing nicely at almost 9-10 inches, and I am SO proud to say this, because I never thought it would happen, he is now eating PELLETS as of two weeks ago!! He would only ever eat market shrimp, or tilapia. Not one thing else. I always wondered if he was a hybrid of some sort, due to his flat upper jaw, and thought that maybe the RTC in him took over the gene, but I don't really think so. He's always smiling, and that's why we call him Joker the Toker.
I thought my giraffe ate alot, Joker eats like he has the munchies, and comes trudging back to his cave with a big belly full of 4 types of pellet. Wish I had his metabolism lol.
