Ok so my 8" JD was rehomed into a 55 gal all by himself about 3 months ago, took him a good month or so to be comfortable enough to beg for food again (his favorite past time). Now I don't vary his diet too much if at all, but I decided one day he'd get a little treat and cut him off half a worm. He's eaten worms multiple times before, but when that worm hit the water he bolted to the other side of the tank and hit the glass a few times before taking cover. I left the worm in the tank over night to find that he hasn't touched it and was still in the other cave. Now I know these guys are supposed to be skittish but I've never seen anything like that before. That was a week or two ago and he's still not begging for food. Guess it's just pellets from now on haha.
