He needs to have 24/7 access to hay. He should never run out of it. Hay aids in digestion and helps keep the teeth filed down, without it you can expect eventual health issues.
He should also be eating 1/4-1/2 cup of a good quality pellet food daily. It varies by pig, some eat more and some eat less. It should be plain pellet, no seeds or "fun" things mixed in. It should also have added vitamin C. Oxbow is a good brand for all of this. If you don't want to feed pellets then do some serious research into diet and nutrition, it is possible to forgo the pellets if you know what fruit/veg to feed.
He should be getting at least 1 cup of veggies every day. Mostly greens like lettuce (red/green leaf), but also bell pepper, carrot, etc. There are lists, if you use google, of what they can and cannot have and how often to feed certain things.
You should also be supplementing him with vitamin c - guinea pigs cannot produce it on their own. Without it, they wind up with scurvy. If you choose the right food and feed the right vegetables then the supplement isn't REQUIRED, but please research diet so you know the pig is getting the vitamin c it needs.
I also have to point out that guinea pigs are social herd animals - you should have more than one. Humans cannot provide for all socialization needs, and we're honestly not with them long/often enough. I also hope that your current pig is not in a store-bought cage: most are WAAAAY too small. One male should have at least 8 square feet of space, and if you get a second you're looking at needing 10+ square feet.
Please, research - should have been done before you got him! Good luck!
