Any bird will take some time to adjust to a new home, make sure the room he's in isn't too quiet as this can spook the bird. Play music and let him get use to the idea you will be making noise and there will be activity in the area he lives in.
Talk to him as much as possible, place the cage near your computer if you sit at one or just sit beside the cage for long periods of time while playing on your phone. Keep talking and glancing at him but don't stare for a long time at his face as this can spook him. Predators stare at birds so you don't want to make the bird more nervous, when looking and talking to him blink your eyes and move your face up and down or around slowly looking around the cage just make sure to not look deeply at the birds eyes and face.
If he's not eating much this is common with birds that have moved into a new home. Find out his favorite treat and offer it to him with your fingers or pin it up on the bars where he will have to come to eat it. It's good you see he's eating, water is the most important right now you want to know he is keeping hydrated, perhaps take a leaf of lettuce or kale and wash it well then leave it semi wet and pin it in the cage near a perch. If he's hungry for it he will eat it but he will also lick the water drops which will assure he has some water.
Searching other sites about these birds it shows they like to eat a variety of fruit and vegetables, a good seed mix containing safflower, oats, canary seed, groats, assorted millet, hemp and sunflower. So offer him a little chunk of millet the same type you give your budgies.
Also viewing a few other sites online show the bird is suppose to be very quiet and shy in a new atmosphere and especially if they are housed on their own and don't have another superb parrot with them in their cage.
Yes, I'd put a cuttle bone in his cage just don't get the smaller package ones that are a proper size for budgies. Get a larger one, the cuttle bone offers calcium and some salt which is good for any caged bird.
