do you clean the filters during the wc? most of those things happen if the water is dirty.

best bet would be clean out the filters.then make sure the water is can add intrepet internal bacteria ( for the other problems like dropsy ) or intrepet fungus away ( for fungus or hole in the head )

How many fish in this tank? This is spring...near summer. This could mean mating behavior. Males and females act aggressively during this time, and may beat each other up if not totally compatible. I don't are the best determination. Without any signs of infection at this time..I'd say keep an eye on him/her in future. If the population is healthy, you may get a pleasant surprise.
Cause I don't kmow your exact setup, I can't say.....Keep an eye on that bump..if it shows any sign of infection...isolate and treat.......and best of luck
