Support Niko's Emergency Vet Visit

Help Niko with his very sudden, unexpected vet visit. This morning, when I got up, Niko was upside down in his tank and has been opening and closing his mouth ever since. I tried to give him a soak to see if he needed some water; maybe there was some food stuck in his throat. He started bubbling at the mouth and has been continuing to gasp since early this morning. I'm so worried about my boy.
