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.
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.
My snowball and my rcs colonies are perishing - succumbing to bacterial infection I believe. I moved house not very long ago and for some reason my YCS and CRS have taken it in stride, not lost any berries or shrimplets at all as far as I can tell. I'm not sure what has gone wrong with those other 2 colonies - I think it may relate to some of the cleaning process of the gravel/tanks or whatnot.
The RCS have a purplish/bluish section on their abdomen and the older ones are the first/quickest to give up but others are following, most have poor colour. They first became ill after being placed in a food-grade bucket I bought from bunnings (but probably didn't wash well enough.. who knows what was the reason as other shrimps did perfectly well in the exact same buckets)
My snowball colony was obtained a few months ago but were compromised by being placed in a tank of doom from the getgo, I never saw any saddles and 4 of the 20 I bought had died over that period. Since moving them to a new setup (with completely new filter/media, new gravel and tank) they have been dying 1 or 2 per day and I now have 5 or 6 left.
Due to time constraints I have failed to mitigate the illnesses in either of these 2 colonies and I'm going to bin the rest of them so I can focus on my other colonies and once they are thriving I will consider setting up other tanks again,
ANYWAY - you win some and you lose some but I know my shrimp breeding hobby will bounce back stronger,
My future tanks will be setup much better given planning and time to do it properly.
I joined the forum after having accidentally bred thousands of mixed-grade RCS in a large 4 foot planted tank. I sold many of these very cheaply and thought "wow how cool I can pay for my aquarium hobby as I go!".
It took some months before I realised truly how fun shrimp breeding is. The process of selection/culling is so rewarding and despite lots of hiccups I have still made progress improving the quality of my shrimps.
I am especially proud of my YCS colony as I struggled and struggled when I first got them, barely managing to get them to reproduce but over the course of the year I now have "hardier" shrimps while keeping the same colour quality as I initally bought.
I look forward to sharing experiences and knowledge on SKF in the year to come.
I really want to thank all the members of SKF who have contributed over the course of 2015 to make this such a wonderful and helpful community I have learnt a lot.
I won't single anyone out for thanks but there are people here who go well out of their way to guide noobs like me through their shrimpkeeping difficulties and they deserve a big pat on the back.
I'd also like to thank the wonderful sponsors here. and a huge thankyou to Nogi for putting in so much time to manage the forums here!
Cheers SKF and may the forum continue to grow and thrive into the new year to come.
love n peace
