Hi, I have a '10 coral cat shark in a tank by itself. I've had it for about 9 months and it has been awesome. I feed it twice a week and it normally goes nuts when the food is in the tank. However, over the past week, I've had trouble getting it to comsume its food. It still gets excited when the food is in the tank, but instead of eating it, the shark carries it around in its' mouth and then spits it out. It acts like its struggling to get the food down, but the pieces are small. I've tried frozen prawn, scallops, shrimp, and shark formula with no luck at all. I was wondering if anyone on here has experienced this before or if anyone know what it could be. Any advice would be greatly appreciated. thanks, Tommy
