Clownfish Skin Disease

[Zakary2003]

My clownfish has these bumps/lesions. They are fairly new. No other fish in the tank (two mandarins, another clown, a tailspot blenny, and a yasha goby) appear to have any issues. This clown hosts a frogspawn coral if that's relevant. I've also seen the female being agressive towards the male.

Can anyone identify the issue? I'm concerned with how rapidly it is progressing.

These are secondary bacterial lesions associated with Brooklynella. Often confused with ich, these lesions are treatable with Ruby Rally Pro and the longer you treat , is the better the outcome. Start with a ruby Rally pro bath for 60 minutes then treat as normal. Mucus generally starts at the facial area as well as gills and spreads across the body producing lesions as it progresses often confused with ich and can turn into secondary bacteria. Other symptoms will be lethargic behavior, refusing to eat and heavy breathing from the mucus.

I have sps, lps, softies, shrimp, hermits, anemones, and a tridacna maxima clam. Is the ruby safe for all of them?

Yes , for sure but always obviously best to treat in a separate tank

There's no way for me to remove all the fish for treatment. My yasha goby and mandarins would be impossible to catch. I think my only option is an in tank treatment, no? I could remove the two clowns and set up a bucket or something for them, but couldn't the infection still stick to the other fish and rocks?

The male seems much worse than the female. In the second photo, that clearly looks like bite marks. Although the fish seem to be paired up, they may be bickering, especially since you saw some indication of that (it might be worse when you leave the room).

That's definitely possible. But there are clear cysts and thickened slime coat, so there really seems to be some kind of disease present as well, probably brook like the other user suggested.

There could be a protozoan component to this, but I didn’t see the stilted swimming typical of Brooklynella. Perhaps that will develop later?

I dipped him in Ruby Rally Pro at 2x strength the day after my last post, then dosed the tank for a week after the other clownfish started showing cysts too. We are now a few days after I stopped treatment and both clownfish are looking perfectly fine. The treatment killed an acro, but it was already in a slow decline after being stung by my anenone when it decided to go for a walk.
