brought home my JD 3 weeks ago and he still hasn't eaten anything i have given it. do they have a main diet? feeders? i tried krill and prawns. its about 7-8 inches in a 140 gal with a small 4 inch RTC that always hides
 
Have you tested the water parameters? 3wks is a long time for a fish to not eat anything....If the water parameters are fine, he is sick.
 
is it facing to the rear of the tank? do you have a smaller tank? jack's can and will eat anything. try blood worms.
 
could he be sick before i got him? my water is fine. he just floats around or just sits at the bottom

since he is that big i take it you got him from a lfs which probably means they took it off someones hands for trade and why did he trade it in? i think you awnsered your own question. he was probably sick before you got him. now you have to diagnose it. i mean if he appears healthy as far as no ick or fungus stuff like that then maybe id treat him for internal parisites just to be on the safe side and keep throwing every kind of food at him and see if he eventually eats something. good luck and hope everything works out for you. keep us posted on he does
 
I have never seen a fish deny frozen blood worms. If he still won't eat, I agree parasites are a possibility.
 
Raise the temp and add some salt, if you see no improvement, treat for parasites. Give garlic a try.
Out of curiosity, what is your water change schedule?
 
maybe hes old and dying, bu that a quess

and i only say this because of his size but they grow somewhat fast

but if not do like they said treat him for parasites
 
Adult fish seem to take longer to come around. You said your water is "fine", did you test it? Sometimes we think our water is fine when it's not. If the ammon & nitrites are '0' and nitrates are no higher than 20 I'd try frozen bloodworms and leaving the light off. I got my Chocolate Cichlid from a fish shop that had horribly high nitrates (180 ppm) and she'd been there months. It took her close to 2 months in super low nitrate water at my house to eat. She might've been eating but I sure didn't see it. All of a sudden one day she scooped up a bloodworm and from that second on she's been an eating machine. So maybe if the JD was in bad water/bad situation for some time he just needs to get used to things and that can take some time. They have to build up their strength and immune system basically. Just a thought. I wouldn't start adding salt or meds, I'd just keep the water pristine with low nitrates.
