      Moderators City: Inner West, Sydney AU Interests: Shrimp, cars, fish, Computers, Cycling/Bikin Posted September 27, 2013 (edited) With the wealth of knowledge from experienced keepers here in SKF, we should have a repository of Shrimp Diseases where people can come to diagnose and hopefully find a cure to their shrimp's ailment.

      Just like in the world of aquatic fish keeping where identification and diagnosis of diseases in fish and known cures are part and parcel of every aquatic forum, so should we have one for shrimp.

      Vorticella

      I'd like to start this database off with the not so uncommon Vorticella parasite which looks like White fungus or mould growth on the shell of the shrimp.
      Vorticella is actually a protozoa of 16 known species, not a fungus at all. Vorticella are aquatic organisms, most commonly found in freshwater habitats. They attach themselves to plant detritus, rocks, algae, or animals (particularly crustaceans).
      Vorticella are heterotrophic organsims. They prey on bacteria. Vorticella use their cilia to create a current of water (vortex) to direct food towards its mouth.
      Typically, Vorticella reproduce via binary fission. The new organism splits from the parent and swims until it can find something on which to anchor itself.

      If left untreated, vorticella have been known to cause the death of the shrimp it was attached to.

      Here are examples of what it looks like.
       

       

       


      Known cures: Salt bath with aquarium salts. Be careful not to use table salt with Iodine.
      Dosage: 1 teaspoon to 1 cup of clean tank water (not tap water).
      Duration: 30sec to 1 minute. You might need to repeat this a couple of times until the vorticella disappears, so keep the infected shrimp in a breeder or hospital tank (could be another cup of tank water).
      Possible causes: Poor water conditions. Increase water change frequency.

      Low doses of the salt bath have been know to be ineffective.
      Ick and fungus cure meds don't work on Vorticella.
      Seachem Paraguard could work as well at the full recommended dosage, since this is a parasitic med. But Seachem have admitted Paraguard isn't invertebrate safe. So only try paraguard as a last resort and drip it into the tank premixed from a bucket of tank water slowly .

      This treatment is in no way a replacement for good tank husbandry.
      So keep up with your water change routines, and removal debris and uneaten food.

      Please add if you know of more diseases, how you cured it, what you tried that worked and what didn't work.

      Cheers.

      Hello!
      I started having some weird parasites in my 10g shrimp tank. I first saw some long and flat worms (maybe detritus worms?)  https://www.aquarium-pond-answers.com/2007/03/trematodes-and-nematodes-in-fish.html.
      Now I see some weird creatures that look like small shrimps (about 5mm long) with shorter antennas and legs, please take a look at the video:
      https://www.dropbox.com/s/q7w9p60lzgr6hji/IMG_9513.MOV?dl=0
      Do you have an idea of what they could be, whether they are dangerous for my cherry shrimp, and how to get rid of them? Could it be Gammarus pulex?
      Many thanks in advance!

      My parents have an aquarium, so I don't know if this will help, but still want to leave a suggestion. They also liked the idea of installing a light strip in it, so they started looking on amazon. I don't know what went wrong, but it broke on the fifth day of use. I think it was a cheap Chinese thing (although the website told me it was waterproof and durable). They asked me for help finding a better option, and I advised them of the smart LED multi-color light strips I used in my car. Being pretty skeptical, my dad still decided to try them. They have been working fine for a month now and don't even flicker. Mom says the fish are happy, lol. I hope my comment was helpful

      It's not looking good. Quarantine any shrimp showing Necrosis, as it can be infectious. Tell us what your water parameters are, and do a heavy water change after that. Increase surface agitation to get more oxygen into the water. A bit of H2O2 (hydrogen peroxide) into the water to increase oxygen might also help the shrimps that have not yet contracted this.

      Sorry to see you have a problem. Try reading the section on 'muscular necrosis' in the below section. You will need to scroll down through it until you see the bold red heading of that description (it is quite a large article covering many problems etc, it is about the 5th item on the first page);   I don't have any personal experience of this but do ask any questions as someone may be able to help. A bit more general info may also  help, your setup, number of shrimps, how long you have had the shrimps, any water parameters you may have etc?

      Hello, I was wondering if anyone here had any first-hand information on these particular pictures. It describes exactly what a few of my shrimp have. The second picture is spot on and most accurate. Thanks

      #4 looks almost like a juvenile female to me, just looking at the abdomen in the top left image, but definitely looks more male in the other two images. The colour suggests it is an adult though, and it’s lacking a clear  so Simon is probably right in thinking it is male, that top left image is just confusing me a bit. If you’re going to get a female, to be sure, make sure it’s got an obvious yellow saddle. That’ll help you know it’s mature as well.
