Hello! We have had our fish for about a month now, and my mom changes the water once a week. She doesn't perform a complete water change, but she does change most of it. Ever since she's changed the water a couple of hours ago, our fish has not been moving at all. We gave the bowl a couple of taps to see if he's alive (we know we shouldn't have, sorry), and he did make sudden movements. I also read that the water might have been too cold, so we added some warm water. He swam for a few seconds and completely stopped again. I have attached some pictures. Could you please help me out? I feel like I'm gonna cry.
