My CK, who I've had for around a month, has survived all of the water changes that occur during the first week of a new tank setup. Recently, he has started scraping his side on the ground. And before that, he developed a small bump on his left side. The fish store I bought him from told me that it could be an air bubble (I'm assuming from when he gulps air from the surface). Does this mean anything?

I know its kind of hard to see, but as I said it's on his left side; this is the best pic I have.

The new tank is probably the cause of the flashing. Are your water parameters appropriate? Is the bump the white spot near his eye?
