Clown fish black spots. Hosting issue or something else

[Justjim]

I got a pair of clowns from a stranger at a swap. The female is covered in black spots as the pic shows. I've had them in qt with a yellow tang for almost two weeks. The qt has cupramine and prazipro dosed for medication. The black spots have not transferred to the yellow tang and all fish are eating aggressively. Could this be from trying to host something in their previous environment that wasn't ok? If that were the case is it something that would heal?

Clownfish can get blackspots from getting stung by corals or nems, but yours has quite a lot. I would keep an eye on it and make sure it is not some other sort of disease or parasite, but my bet would be on sting marks.

Looks like stings from a host. What has it chosen as a host?

 

[Justjim]

I got it from a stranger and didn't get enough info. I've been treating it aggressively so I'm leaning towards a bad host rather than black ich. The fact that the yellow tang is clear back that up. My main question is will it clear up if it was a hosting issue?

 

[Small triggers]

Hypermelanization.......

 

[Justjim]

That is the correct term. Will it clear up?

 

[jedidad]

Yes it should as the host gets used to the clown it should stop stinging it. This happened to one of mine when it hosted a torch coral and it went away after a while.

I dosed another round of prazipro. This time I used 50% more than the recommended dose. Everyone is eating well and the yellow tang is still clear. I'm waiting another week and releasing them into the DT. I have an anenome in that tank and hopefully the transition will go smoothly and over time the spots will fade.

I noticed similar black spots on my clown yesterday and panicked a bit after search the web for what it might be. It's hard for me to tell from other examples I've seen on the web if he (or she) has hypermelanization or black ich. My purple firefish isn't showing signs and it's hard to tell if my blenny has spots because of his coloring. I have no other fish in my tank. I do have a torch that the clown does swim near but I haven't witnessed hosting.

Can anyone confirm hypermelanization or black ich?

Thanks...Keith

Reviving an old thread:

I have a pair and only one is showing signs of hypermel’. Wouldn’t both clownfish have the spots if it’s a hosting issue?

Behavior-wise they are acting fine and eating well. I put theclownfish with the spots in QT and treated it, but the spots did not fade or get worse. I thought some time away from my coral would make them fade and the medication wouldn’t hurt as well. However, I’m back to square one with this.

How it looks today:

Those are sting marks from the non natural hosts. A lot of them they are from polyps that the clowns tried to use as hosts.

It's odd that it's only on one of the clownfish, though. The spots have not changed in months, too.

Psychological? Hormonal? Reaction to my lighting? Seems like something long-term, maybe permanent by now. I never see these clowns touching polyps. In fact, they don't even acknowledge my two BTAs.

Should show clearing in 48-72 hours.
asdure it’s getting a proper diet and add some garlic to its foods as a booster for immune system

How are the clowns doing

I have some clowns that have taken to hosting hammer corals… little guy in the lower right. That or something with nematocysts died and released cells into the water column…
