Hmmm now that is unusual.

Did the shrimp recently molt?

Black Spot disease is a bacterial infection. I researched this several years ago when I had a shrimp show up with it.

Here's some info I got from a hatchery:Spot diseases
Brown spot shell disease, burned spot disease, rust disease, shell disease, black spot disease are the types of spot diseases which are caused by a group of bacteria belonging to Vibrio, Pseudomonas and Beneckea. Maintaining the quality of water within the optimum range, removing the dead and infected shrimps, reducing the stocking intensity, providing good nutritious feed, incorporating terramycine at the rate of 0.45 mg per kg of feed for two weeks, bath treatment using 0.05 to 1.0 mg of malachite green per litre of water are some of the remedial measures suggested to counteract the incidence of viral diseases in prawns.

My shrimp did not die from this. It went away when the shrimp molted. It returned again but went away pre-molt and never returned. It is possible for the shrimp to die from it, but with clean water and care it doesn't have to. I didn't use the treatment they suggest but you can give that a try as well. Copy from another webside.

You said you found one of his molted antennas (long white thing in the sand) - After the molt, did the black spotting go away?

~Bruce

It wasn't just one , was four and attached to a white little something, that's why I said it should be the mold

And in that day he had just a slight black dot that I didn't notice, I only saw it when I rewind the saved images. I have an ip camera recording

The black dots started to appear after that

I also thought it could be the fact that he keeps swimming and "walking" through the zoanthus I have andyhat the zoanthus made that to him as it has done once with my clownfish that got a little black spot

But now it got really big compared to the little black bruise on the clownfish that went away

Hmm. Okay. Beginning or growing worse after the molt.

I'm not well versed (or even not at all versed!) in crustacean disease, but I know that the local lobsters have had trouble with their shells lately, due to warmer temperatures and lower pH.

The only thing I can suggest at the moment is to make sure that all of your water quality checks out; pH, calcium, Alk, etc . . .

I don't really suspect the zoanthids - unless yours is a remarkably powerful zoanthid.
