I have a female betta that is refusing to eat a lot of the things I throw at her. I got 3 at the same time and they're from the same brood. The other two are also female and eating fine, so I don't know what's wrong. I've tried feeding her peas, freeze-dried bloodworms, and pellets. However, I've noticed she is older and fatter than the others. I think she has an egg sac which is why her tummy is round. Could this be causing her to act differently from the others? Is she pre-occupied with looking for a male betta to fertilize her eggs? Currently I am housing her in just room temperature water but I plan to move her to a warm tank tomorrow to see if that helps. Anyone with such experience?
