Thank you so much!
Our poor little Calico Moor died this afternoon

...he had a bunch of white spots, Ich I think, breathing fast and hard and also emaciated a little before he died. Unsure whether his case was too far along or Super Ick Cure (API) isn't so super, but it did seem to clear up our Black Moor.
It's really, really tough, but you know this...Fancy
Goldfish are so sweet and loving...
The Black Moor still looks healthy after recovering over the weekend, but I worry a lot because this Ich, or whatever, must be real stubborn... Was wondering what there was to treat him now while still healthy to make sure the bugs are gone!
So thank you very, very much for the rec., it's very timely and very much appreciated, plus someone mentioned he may have a superinfection so it's really great you're recommending a treatment that gets a bunch of diseases. Some posters had recommended Jungle Antibiotic Food or Antibacterial Food and all the user reviews seem good but I can't find the food anywhere, may not even be available any more.
Thank you again for your advice and well wishes,
Steve
