Shrimp black Spot

[Micro Reef Tank]

Hi, I don't know if this is the place to post my help demand,if not plz excuse me

Does any one knows what is this and if there is something I can do regarding this black thing in my shrimp

It has it in both sides as some little spot in legs and body

Hmmm now that is unusual.

Did the shrimp recently molt?

Moved to Invert Forum

Calling in the #reefsquad. Anybody ever see something like this on a shrimp?

That could be black spot disease. I don't believe there's a cure for that, but I haven't read about it in some years.

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.

Thanks to all that are trying to help

I bought it on the 4th march then this Saturday I found some white long things he has in the sand, sorry English is not my natural language.

 

[Micro Reef Tank]

So I guess he did a molt

sorry English is not my natural language.

My either

But I can read and understand almost everything here besides some words that I check online

I read somewhere that yes it's comes and go with molt

But also that it may lead to a hole and that they die

 

[Micro Reef Tank]

Só as everything in a Reef Tank all can happen. But I don't find many info and reported experiences like this

 

[Micro Reef Tank]

The main concern is that it goes to my other inhabitants

 

[Micro Reef Tank]

He is the only shrimp I have so it may keep it with him

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

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

And today

 

[Micro Reef Tank]

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

 

[Maritimer]

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.
