Sick Dogface Puffer! Ich?

[DGarrity]

I have a sick dogface puffer! He has ich I think. I treated with weco nox-ich (Malachite Green) after being recommended by a local fish store. Seems it didn't work or only provided temporary relief. Gave him a FW dip two nights ago. Hoping it's ich and not velvet. Would prefer to stay away from copper if possible. He is the only specimen in this tank. I tried to give him some Astrea from LFS without QTing them first. Big mistake. He is flashing pretty consistently. Also hiding a bit more and his appetite is up and down.

Pics of the full fish may be helpful.
All I see looks more like it’s spines or sand stuck to it.

Maybe he has nothing and he was just not hungry and flashing a lot and I'm just a paranoid fish dad. Idk. This is my first foray into saltwater and I just love this little guy. Don't want him to feel bad.

These are some older videos when he seemed a little happier and more interactive. Before the flashing and erratic movements started.


Here's another video of him curled up and showing a little more dark coloration pre illness.

Hi, welcome to Reef2Reef!

Those spots in the image on the puffer's skin aren't ich, they are too regular in spacing.
Malachite green does not work well for parasite control in marine fish, I would avoid it.
In one video, the puffer is breathing fast, so I can't rule out velvet here.
I would consider treating with coppersafe, and then try prazipro for flukes.
