Is there something wrong with my beta fish?

I brought him home looking vibrant and healthy, but it seems as though he is afraid of everything. Not being able to buy a large tank yet, I bought a glass bowl and put some transparent, rounded gem-like things on the bottom so he would have a little color. Yesterday and today, I fed him correctly twice each day. I do not tap on the glass and continue to be very gentle but everytime I come near the glass bowl, he seems to be so afraid. Today, I've realized that he's afraid of ANYTHING put near the glass bowl, even my finger when I try gently.

I read that Betas are supposed to follow and want to chase things, not shy away.

Could someone please give me some more information? I really want him to feel safe and loved. I feel really bad not knowing what to do about this.
