Our new goldfish are doing well.
They've responded well to the medication and all of their ick spots are gone. They're still a bit weirded out being in such a small tank, but it won't be for much longer. I'll probably start moving them into Santino's tank after another week or so of quarantine. I've been trying to get a photo of all four of them together for a while now, but have been unsuccessful. They either won't hold still for more than a second or they turn away from the camera or both.
I've got lots of photos of blurry fish butts.
