Welcome to the forum and to the wonderful world of Betta keeping....
Its not uncommon for a new Betta to go off food for several days to a week when first introduced to his new home-especially with a filter since sometimes the water movement will be something new.....
I would offer food-then remove it in 15-20min if he doesn't eat it and try again later.....once he gets adjusted he should start to eat.....to be sure it is a adaption issue we need some more info....
How big is the tank, any live plants, type/amount of additives used, how did you first acclimate him to the tank when you first got him-what are your water change plans and type of filter....and what kind of food....
You need to turn the lights off at night-Bettas don't have eyelids and need a dark and light cycle and if the lights are on too long you may end up with algae problems.....If you don't have live plants-I would keep the lights on for at least 6 hours and no longer than 8 hours....
You may or may not need a heater, however, its a good idea to have one on hand-your goal is to maintain a somewhat stable temp in the 76-80F range-usually with a healthy Betta they can tolerate the gradual temp change from day and night of about 10 degrees or so.
You do need a thermometer to monitor both the tank temp and water temp of the replacement water used for water changes.
Can you post a pic....
