Black Spots on Foxface

[J-Rob]

I did a water change a couple weeks ago and my Foxface (along with everyone else) didn’t enjoy it much. It was the 1st water change for them.

When she came back out she had a skuff one one side and a spot on the other. I thought she’d probably gotten stuck behind the rocks. My wife vacuumed a few days ago (1st time for that too! lol) and she’s been a little bashful since and hiding a lot.

Today when she came out she had a bunch of black spots on her. :/ I hope it’s not Ich. Hopefully someone here can give me a little guidance...?

Tank is only 3 months old...
90 Gallon
Perimeters yesterday were:
Ammonia-0
Nitrite-0
PH-8.2
Calcium-400
Phosphate-.25
Nitrate- 10ppm

Not other fish have symptoms.

That's Black Ich. Treat it same as flukes with a praziquantel product like Prazipro.
