IME this is usually 1. temp related 2. the amount of diluted oxygen in the water.
Try using an air pump set to minimum. Mine usually remain near the floor during the day and many remain there at night (most surface). If you don't have a pump, do more daily/2 wc .... like about 10 - 20%. Hope they all make it.
About the number of fry ..... I'm guessing you currently have between 100-200. Newly hatched bettas don't look .... much but if you count them, you'll be very surprised.....
