I just can't give him bigger tank at work. He is i think approximately 17 or 15 month old. I try change him every 3 days 100% of the water. But i always make sure he eats all his food it never go to the bottom.
Also temperature at work 70*.
At home i keep my betta at 74* and my bettas old.

If he is in less than one gallon, you must do daily 100% water changes. Ammonia builds up fast. And I honestly think less than half a gallon is inadequate for a betta. Regardless of how much you are feeding him, they constantly secrete ammonia through their gills so regular water changes are necessary. Every three days is not enough, especially in less than half a gallon.
Also, 70 and 74 is too cold. Betta are tropical fish and need to be kept in tropical temperatures, which is about 76-82.
@Anhel, bettas can adjust to temperatures but that doesn't mean putting them in 70 degree water.
@RillC, even if the light raises it a few degrees, it is too cold. The temp should be at about 76-82. Also, using a light to heat the water isn't a good idea because when you turn the light off at night the water will get cold again fast.
