Help Sick Severum

[JC09]

Hey guys, so I added a couple new fish over the last week and now my Severum is acting up. Shes scratching and twitching more than he normally would. She is still however eating like a pig. Water params are all good. Ammonia and nitrate are 0. Been doing 10% daily water changes and 20% today. No other fish is showing any signs. At first i thought it was a dominance sort of thing. Shes been the queen of the tank for quite some time now before I added in these fish. You can see in the photos that she has some white spots on her, not ich. I believe them to be from the scratching but im not sure.

Heres a quick video (sorry about the poor quality, and dont know how to embed): https://www.youtube.com/watch?v=OMQdTINoGq8&feature=youtu.be

Having trouble uploading pics as well, hopefully this link works. One pic shows the spots and the other shows the scraping on his side.

maybe medicate for parasites as a precaution?

Try to get into the habit of quarantining your fish, it can save you big headaches. I would start by giving this fish salt and heat treatment and see if there's any improvement. If not, you may need to try another med but I wouldn't medicate unless you know what you are treating for. Most people do more harm then good, by giving wrong meds, its a good way to severely weaken your fish's immune system.
