You shouldn't be feeding so many fruits. Only feed fruits about once or twice per week at most.
Guinea pigs should get about 1 cup of leafy greens and other veggies per day.
You should start off with some Romaine lettuce. Don't feed Iceburg because it has next to no nutritional value. Also, feed some bell pepper. Nothing spicy however. Maybe a baby carrot. Those should only be fed one baby carrot per pig, per day.

**Also, look at the stick thread nutritional charts that Ly&Pigs made. They are so helpful. Use the sticky threads in all of the forum sections. They are so helpful. **

Cover the veggies in water, and if the pig eats them, they could be getting most of the water they actually need.
But since you got the animal two days ago, the pig could be still adjusting.
Are you offering hay 24/7? What about a high quality pellet? The best brands to feed are Mazurri5664, Oxbow, KM's, and Sweet Meadow.
Good Luck With Your New Piggy!
