This is the strangest thing and I have no clue what it is/was. :Help!:
I picked these up a few days ago and put them in a quarantine tank - thank goodness!! The next day they were absolutely covered in yellow bumps. yikes I thought it was ich at first, but the spots seemed larger and were yellow.

I added aquarium salt, started raising the temp, and also added Quick Cure at half the dose.
The following evening, I noticed one of the fish nibbling at and appearing to be removing the spots from the other. By the end of the night, one was almost spot free and the next morning the other was nearly spot free as well.


There is also a third that was covered with the same yellow bumps and those bumps are gone and have been replaced with a few white spots that look more like ich. The other two are now completely normal looking. All three are active and playing around in the tank like nothing's wrong. I'm going to keep treating for several more days.
It's just so strange the way it showed up so suddenly and disappeared the same way. What do you suppose this was? idunno
I can't look at these pictures without feeling creeped out - I felt contaminated when I first noticed it and am afraid of water changes. blinky peek a boo
