So I noticed after Hewbie eats his swimming slows down and he breathes a little heavier is this normal or a sign of parasites/flukes? Also I just realized the crab I threw in almost a week ago was still alive and moving despite breaking off the claws and legs. I just crushed it up more and Hewbie finished it up. And I know puffers store food in their bellies so that’s why I ask if the behavior is normal.
