Unfortunately my resident clownfish is showing raised white irregular spots and a slight haze to the upper body. It's hard to photograph because it's only visible on camera when the light hits, but very visible to me.
We've had her(?) for almost a year but his new clown partner (smaller) was added about 10 days ago and seems ok. The only other fish in the tank is a bicolor blenny.
I have a 10 gal QT but I've never used it. I'll need time to make water and test it, but it'll be uncycled which feels risky. I also ordered Ruby Rally Pro for delivery tomorrow and am seeing a 90 min dip followed by metroplex in QT every 3 days with a 50% water change. Do I only treat the one clown?
Any advice appreciated. Thank you
