OMG. All of this was mentioned in this one thread. Do any fish actually live through this? o_O

I wish my fish would get something so I could use all these cool sounding medications. :unsure:

I don't know what most of it is.

@Eholceker Instead of using formalin, I would go with a H2O2 bath instead: https://humble.fish/community/index.php?threads/hydrogen-peroxide.21/

But treat at 150ppm (5 ml of 3% H2O2 per 1 liter of saltwater.)

My research indicates that concentration has the same effect as formalin, but not as toxic.
If I drain the tank they were in and fill it back up with freshwater and run the tank for a few days fresh will that essentially kill everything in there as well?

No, because it has been proven that velvet can survive in freshwater. This is the best way to sterilize a QT without having to drain it:
  1. Dose 100ppm chlorine as per this guide: https://dec.vermont.gov/sites/dec/files/dwgwp/DW/chlorinedosageemergencydisinfection.pdf
  2. Circulate well for 48 hours, and then use sodium thiosulfate to neutralize the chlorine in the water. Most pool places sell a product called Chlor Out which contains sodium thiosulfate and is safe to use. You can use this website to determine how much sodium thiosulfate to dose: https://www.edspumps.com/water-treatment/documents/Antichlorination.pdf
  3. After you are all finished, your alkalinity might need to be raised. If so, use baking soda as per this calculator: http://reef.diesyst.com/chemcalc/chemcalc.html
P.S. I've also attached a spreadsheet you can use to determine all of the above.

Moved all the fish this afternoon. They all did really well with the h202 bath.

That's a mixed bag I guess. 😶
Not sure what happened with it. I had the fish for 18 months and I know they have a very limited life span. Thinking it may have been it's time coupled the QT stress. Ii pretty much fed the fish as much as they could eat for 2 days. Just dosed 20mg of the CP and will do the other 20mg tomorrow. Then on friday I will transfer the fish again with an H202 batch in between. Hopefully this is the end of whatever it was. I also haven't seen any flashing since I moved the fish.

Most sources claim they have a life span of about one to two years.

So still away and will be back on Thursday. Been watching the fish on my ring camera. It's been 9 days and haven't seen any flashing. All fish are eating very well except for the rabbitfish who still prefers to graze on live macro verses earing in the water column. I put a half a pound of redo ogo in the tank and it looks like ate about half of it already. Not sure if it was the CP, h202, or the transfers but so far so good.

@Humblefish so have been home since Thursday and have noticed know flashing. The one Randall's still has a few white spots on its body. It's been there since Thursday with no change. Typically how long do ick spots remain on the fish. Not sure if I should add the fish to the display or not.

7 days is the max that an Ich trophont will feed on a fish before dropping off. You may still see the white spot for another day or two, however.
