I'm sure I'm jumping the gun with worry, but my new 8" Male JD has not eaten yet. I recently adopted him from a couple who had him in a 40 long and put him in a well established 55G w/dithers. He has magnificent color and is healthy as can be. He is swimming/acting fine, but has shown no interest in food yet. I've only had him for 24 hours, so I'm not too worried yet. Opinions?
