Betta Not Eating

[HRPFG2]

I bought a new betta I let it get settled in its new environment, it's been about 4 days now and everytime I try to feed it pellets it will chew it and spit it out. What do I need to feed it ? or what should i do ?

First off, can you answer these questions? How big is your tank? Do you have a heater? Is your tank filled with silk plants and hiding places? They can go a couple weeks without food if need be, but hopefully he'll start eating soon.
