New ranchu with white spots, ich/fungus?

So, I got 2 calico ranchu shipped to me yesterday from a goldfish breeder. They were in the bag for about a day. There was a lot of peeled off slime coat in the bag. They looked good yesterday apart from my fine sand sticking to their slime coat.

This morning the ranchu with more black coloration has different sized white spots on him (the other fish doesn't). They are not "fluffy" like a bacterial infection but more like a cloud texture, if that makes sense. There are some on his wen, scales, a lot on his tail fin, some on his pectoral fins. There is one spot where some slime is coming off of it, which makes me think fungal. The breeder said to add salt since it's likely from stress.

I'm wondering if you guys think this is ich or a fungal problem. Meds are banned in Canada but I saved a 16 fl oz bottle of Rid Ich Plus (i'd like to use this only if absolutely necessary since it's the only med I have) and i'm going to pick up some pickling salt w/ no additives in a little bit and start with salt regardless. I have some Kanaplex left as well but not enough for water column dosing.

Instructions for what to do would be really helpful as well. I'm kind of panicking and want to do the right thing!

Note: the very fine spots on his scales on the top of him is the sand sticking to his slime coat, it's in a couple pictures

 

Yep, looks like ich.
Gradually raise the temperature to 80 degrees Fahrenheit, one or two degrees per day. Before beginning salt treatments (with non iodized sea salt, without taking agents) do a 50% water change and remove any live plants or snails. Add 19 grams of salt per gallon (a 0.5% concentration), (dissolved completely in warm aquarium water first) to the tank in five separate doses, 12 hours apart. Every day vacuum the bottom to remove any fallen if I packets, and be sure the replacement water has.0.5% salt concentration so you don't dilute your treatment. Continue treatments for about two weeks, by the end they should be ich free.

It is recommended to use melafix after the treatment to prevent any secondary infections, and the whole time the water must be in great condition. (Also, if it seems to worsen in the middle, don't worry, it's just the ich's life cycle speeding up.)

I hope this helps, you have beautiful fish, hopefully they'll be better soon!

Thanks for the reply. I added 8 tablespoons to my 40g as that seemed to be the general amount I could find on other goldfish forums. Should I add more?

I'm also genuinely curious as to why 80f is recommended if i'm not using heat to kill ich? Will they not mind the 80f to increase the life cycle? I was doing more thinking and I was wondering if using salt and rid ich plus together is a good idea since they could work together to heal the fish and also kill the ich?

The little guy in question has been doing great today regardless... he eats his repashy like a champ, finally learned how to sift the sand (which they've been doing for hours now), and they're both wiggling all over the place non-stop.
