Newbie, a couple of questions, brand new tank, water etc, but betta isn't eating

acclimating him means to float him in his cup in the clean tank for awhile, then releasing him into the tank.

Update:

He's eating!
Today he showed some interested when I was shaking the food bottle around and didn't swim away when I lifted the lid, so I put in some pellets and he was eating them up. One thing I noticed, he doesn't like water logged pellets, he likes fresh crunchy ones. So I will feed him once or twice a day and do it only when he seems hungry rather than when he's not looking or doesn't care, so that he doesn't suddenly get hungry and find nothing but water-logged pellets.

I would feed him 2-3 pellets twice a day. I'm glad to hear he's eating. Just keep offering the crunchy ones.
