When contemplating the optimal quantity of food to administer to my Betta fish, how can one precisely gauge the right amount that promotes health without overindulgence? Is there a specific weight or volume I should consider when determining the ideal portion size? Moreover, could the frequency of feeding, along with the age and size of my Betta, significantly influence the overall dietary requirements? Should I adjust the feeding regimen during different life stages of the fish? Would the type of food being offered, be it pellets, flakes, or live feed, necessitate a reevaluation of how much is appropriate? Additionally, might factors such as water temperature or tank conditions alter their appetite, thereby affecting my feeding strategy? How can I discern when my Betta is satiated without risking underfeeding or overfeeding, both of which could have detrimental outcomes? What signs should I be vigilant for, indicating that my feeding practices need recalibration?
