I have had a community aquarium for going on two months. This is all new to me. Over the past week, I have noticed that my Zebra Danios and Brilliant Rasboras stomach areas are all starting to bulge. From the research I have done so far, I am starting to think that I may be overfeeding them. I feed them once a day, in the evening what they can eat in less than two minutes. In the past few days, I have reduced that to one minute out of concern for this issue. I started out with flakes but switched to pellets last week of the same brand. Extreme community crave. I have attached images for reference. Any ideas/help would be greatly appreciated!
