What’s wrong with my clown

[Bobothegreat]

i noticed these spots on my clown today does anyone know what this is?

 

[DancingShark]

hypermelanization maybe.

Is she hosting any coral? If so see above. If not could be black ich.

A freshwater dip should show the flatworms that fall off if it is black ich. A better photo as well, coral stings tend to be quite uniform to each other with a clear outline where the sting was.

Prazipro or ttm would be treatments of choice. Lifecycle of black ich is 5 days easy enough to break with ttm and a fallow period. But unsure how long needs to be fallow with black ich. Have only dealt with fw black ich personally and is completely different.

Prazipro is more reef safe than copper usually only effecting worms in the tank, feather dusters etc.

That’s nothing to worry about. They are sting marks from them trying to host in a new coral/anemone. They will go away

How is fish behaving? ( breathing, itch/twitch, swimming up to powerhead? )
If any of above, may be a common disease with clowns known as Brooklynella which is caused by an infestation of the protozoan Brooklynella hostilis. It is most closely and commonly associated with Clowns, Damsels and other smaller species and labeled as Clownfish Disease. This type of parasite is similar to other parasites, and requires a fish host on to survive.

If no symptoms listed above, then it may be Black spot disease which is generally on tangs but if you see tube worms then there is a chance the spots evolved from them. Black spot disease or labeled black ich is caused by an infestation of tiny Paravortex turbellarian flatworms. After feeding for about 6 days and sucking blood near gills to achieve growth, the turbellaria falls off the fish and finds home in the substrate.

Once these worms start feeding on a host fish they acquire pigmentation, which causes the appearance of black spots about the size of a grain of salt on the body and fin membranes. The worms have the ability to freely move about on fish as the spots do not always remain stationary. On light colored fish they are easy to see, whereas on dark colored ones they may go unnoticed at first.
As with other parasites on the surface of the infected fish, the fish itself will scratch up against objects or the substrate in an attempt to dislodge the parasites, and if the infestation is allowed to progress the fish become lethargic, lose their appetite and colors, rapid respiration develops, and secondary bacterial infections can invade damaged tissue sites. If surface infections develop, treat as with any other bacterial infection which includes a freshwater dip.

If the clownfish acts completely normal and the black spots don't seem to actually bother anything or the clownfish, I wouldn't worry about it.

My clownfish had the same problem weeks after I added them when I added my Toadstool. Black spots appeared, and within a month or two all disappeared.

 

[Bobothegreat]

I had recently added a zoa right now it’s my first and only piece of coral

 

[reef lover]

I doubt its melanization from a zoa...i would fresh water dip....

 

[Bobothegreat]

I just tried to search it but what exactly do you mean fresh water dip. Non saltwater? Like just rodi

One of my clownfish is hypermelanized from hosting paly/zoas. I don't remember which.

 

[reef lover]

Palys i could see but most zoas dont pack that much punch.

It happens with toadstools from what I've seen. My clownfish tried hosting and got stung.
