I'm actually hoping his kok will not get huge. He was with a female and it had gone down some when the pictures were taken, however, I don't like it when they get so big. Reminds me of a big, external brain on top of their heads! If he's hungry, we have plenty for him to eat here... Hikari Cichlid Bio-Gold, OSI Flowerhorn, and 2 types of Chingmix. Really excited -- he should be here in 1wk.
