White Dot Parasite In Tank (pics Attached)

HI Friends,

I'm turning here as a last resort. I've had my 90G freshwater tank up and running for 10 years. White dots began to appear on the aquarium glass about a year ago (I pushed a bunch of them together when I was cleaning the tank to show what they look like in the pics). Before that I introduced a baby blue severum to the tank about 6 months prior - not sure how anything suddenly got in my tank. I'm decent with my water changes, I use purigen, and I have a big HOB filter and a canister filter. Water parameters are all normal.

I've treated the tank with Seachem Paragard numerous times in the last year and also given my fish numerous rounds of Metroplex treatment. I've raised the temp into the high 80s and I move between high 80s and high 70s... when the temp is lower I feel like the white dots multiply. I haven't been able to get rid of the white dots and this week my 7 year old Convict fell victI'm to the disease (she had a white growth on her fin and she started to lay on her side and not move much). I have a 10 year old Blood Parrot and a 1.5 year old Blue Severum, they shake sometimes which tells me that something is wrong with them. My Blue Severum has a white growth on one of his fins... otherwise no visible signs of parasite on their bodies but they shake a lot.

Can anyone help me identify this disease or recommend other courses of treatment?

Could you get photos of the dots you say are on the fish? I've never seen anything that's a disease create dots on the walls like that, but I also don't know everything either.

My Blood Parrot doesn't have any suspicious markings but here are some photos of my Severum. I tried my best to capture the white growth on his fin at different angles... you'll also notice the white specks all over the glass. There's one photo I included where I circle a mark on his head... about a year ago when I first noticed the white dots in my aquarium, I also noticed that it looked like my Severum's skin was deteriorating... multiple holes were appearing on his head (3-4 holes). That's when I first started treating the tank with paraguard and the hole quickly closed up but the wound has taken some time to regrow "skin". Not sure if that's related or not but I didn't see holes on any of my other fish so once he got better I stayed focused on trying to get rid of the white dots in the tank.

Thanks,
Thomas

 

The picture with circle around hole from year ago is hole in the head [ HITH ] ..Vitamins and cleaner water . Do you run carbon regularly in your filter ?
The spot on the fin ? Do you think that is the same thing as the floating spots ?Could the spots you gathered be like seed shrimp ?
Some times there is some type of excretion from hole in the head I think ?

I run purigen in my filters instead of carbon.

I don't think the spot on the fin is the same as the spots on the glass but I honestly can't be sure. I just know that since the white spots started showing up ive noticed strange behavior and sickness in my fish. I've been watching the white spots the past few days... I don't think they're moving around and it seems like seed shrimp move around. Any other ideas or photos I can try to capture?

In regards to HITH, I don't think my Severum has it anymore. What I circled in the photo is a scar from when he had it and it's slowly been filling back out.

Thanks!
