I am having some problems with my fish? Please help?

The fish might of have busted his Swim bladder. I had a fish that after being stressed out he looked like he was twisted and falling apart but really he busted that organ. Weird but also maybe if you wasted the tank and gems with soap you might have not raised it out all the way and fish can get sick from the soap. Just an idea, Just make sure you don't stress him out anymore. Try going back to your old food if your not seeing any results. Hope I Helped!!!
