Recommended Posts

Today i have notice that one of my rilli shrimp with was showing translucent body which looks far from normal. i have lost quite a few shrimps to this disease before and attribute this to planaria infestation(saw a group of them actually attacking an adult shrimp and killing it).

But this time the tank is planaria free and i guess i was wrong at the first place and there must be something else behind this. please have a look at the pictures and suggest me the probable cause and remedies for the same. Thanks in advance.

Have a look at the shrimp disease and diagnosis sticky, you should be able to find it there.

Sushant,

 

that looks like the condition called Muscular Necrosis. 

It's in the shrimp disease and diagnosis sticky thread.

But what causes it is still undetermined yet. It could be an infection, or it could be caused by poor water conditions.

 

First thing to do is to remove and separate it from the rest of the shrimp. This will ease treatment, and avoid further infecting the other shrimps. Put it into a separate container, with some tank water, then slowly drip in clean (conditioned) water over the next few hours.

Would be even better if you can get your hands on RO water or Distilled water. 

 

Add some blackwater extract if you have any. And a couple of IAL leaves.

Add some blackwater extract to the main tank as well. It won't hurt.

 

While that is up and running, test your water and report back with your water parameters.

Agree with jayc, symptoms are very typical of muscle necrosis.

Sushant,

 

I should have stressed the urgency more.

 

You need to act FAST!

 

That shrimp is already very advanced in it's illness.

It might already be too late. But you can try separating it and giving it clean water with the correct parameters for a Rilli/Cherry.

I found one of my cherries like this a few weeks ago but couldn't find anything out about it until I read this post.. Have since removed the shrimp with the same symptoms :(

Here's a study of the Illness,

It's a pdf.

Thanks for the link to the article. 

I read it.

 

It's essentially an article to prove that muscle necrosis could be consistently reproduced and, confirming that the disease has an infectious etiology.

They succeeded in this trial. Which means they could reproduce the disease, and confirm it is infectious.

 

There is nothing in this paper to suggest there is a cure.

 

The paper however, does mention that there is a non-inflammatory and an inflammatory versions of Muscular Necrosis.

The non-inflammatory condition possibly caused by environmental changes such as sudden changes in temperature, salinity or dissolved oxygen.

The inflammatory condition being caused by a pathogen (bacterial or viral).

 

Although they did not see any casualties in their short 4-5 week study, this is quite different in the shrimp farms where casualties are seen. And certainly different to the dwarf shrimps we keep. Being smaller then commercially farmed shrimps, the dwarf shrimps will see casualties in a shorter timespan.

 

Unfortunately, this article adds nothing to what we already know.

There is no cure yet. When the issue is visible, it is already usually too advanced for a full recovery. Not impossible, but certainly difficult.

Isolate the infected shrimp, and correct any environmental issues like temperature, water parameters, and oxygen levels - this still remains as the only possible action.

ps.

 

Even if your shrimps are healthy, it pays to read the Shrimp Disease and Diagnosis sticky. 

So you recognise issues if and when they do arise.

      I am. I’ve looked at a few vendors. I ha w a buddy ordering from Aqua Huna in a few weeks, but I honestly don’t know if them import or tank breed. I know Flip tank breeds, he’s from my home state. I don’t know, but I have time to decide. I’m in no hurry.  Does the vendor you’re talking about sell only reds, or does he have other colors?

      I will consider it. I have an agreement with my wife that $100 a month each is our hobby allowance, and am behind on that by the tune of 6 months already at the moment. Patreon's and forum subscriptions count towards that so it may be a bit unless I sell some stuff (which is likely). I've owned a message board and been a moderator on several and understand server costs and the work that goes into these endeavors and particularly the difficulty of breaking even now that so many folks just use Reddit, FB, Instagram and so forth. It's a tough balance to give member perks to paid subscribers and not leave the nonpaying majority feeling like they can't enjoy the full forum. I admin'ed a corn snake forum where the owner decided to not allow nonpaying people have the ability to edit posts, and it resulted in a ton of members not sticking around -and the downfall of it being a popular place to post. I think to this day the most popular thread on that site is titled, "Show us you pets," and the site owner would not let me fix the typo. (insert roll eyes emoji) All of this to say that I understand restricting some privileges for non-paying folks, as well as the potential for free members not sticking around that it can have. For the time being, I will mark forums messages as spam to keep my phone from alerting me all day and hopefully kick a few bucks a month your way later on. I love international forums regarding our hobbies and the different approaches that seem to be regional and think these can enrich us all! Cheers, and thanks for the explanation.

      I believe those settings are only enabled for paid subscribers.  Consider supporting the forum,  your knowledge and experience will be most welcome here.    Just checking that you are clicking the "Notification Settings" as per the image below right?

      I was wanting to change my settings so that I do not get an email alert every time there's a reply or reaction to a post. Is this something that is disabled for new members?

      You're in the US, no? There's a guy on another forum who breeds nice CRS and sells them for $1 each +actual shipping. Home bred, hardy and beautiful shrimp with lots of positive feedback. Not sure of rules regarding crossposting, so will hold off for now, but if rules allow I'll post a link. Or PM me when you are ready. He's had this colony for years, so no need to rush. I only mention this because most vendors sell imports for between $5-10 each.
