Goldfish with Whitespots and Dojo Loach with ring round body. Any ideas?

[Kevc44]

I recently bought 2 Dojo Loach to go in my Goldfish tank. After a couple of weeks i noticed tiny white spots all over my Goldfish. They weren't swimming very well so i isolated them and had a big clean. It seemed to clear up but then one got sick and died after a few days. Now one of the Loach has developed a large ring around its body and it can't swim properly.
Any ideas

The white spots are probably ich and it was probably introduced with the new fish. If you didnt treat the tank for ich it is probably still in there.

Are you able to post a photo of your dojo loach?

Can you give more details on the tank? Size? How long has it been set up? Water parameters? Anything detail you can give might be relevant?
