A bit further explanation behind what I base my feeding amounts off of . Partly the instructions on the Bio-Gold box, which say to feed 2 to 4 pellets 2 to 3 times daily based on the betta's size, and partly based on what the other betta people feed at fishforums.net. Many of them are successful betta breeders, so I trusted their judgment. On average, my guys get 6-7 pellets daily throughout the day (several small meals are supposed to be more natural), again, with one day of fasting per week. Amounts vary if I add in different food types, a variety in diet is also supposed to be helpful for a healthy, happy betta
