Hello everyone, 

ive had my Taiwan bees for maybe two months, and yesterday I found one of them dead. Part of the shell had turned drown and now I see this on another of the shrimp. I tired to do some research, but I’m not sure what the disease looks like on a Taiwan Bee. I’ve also read that the brown color could possibly be from molting. Is there anything I can do for it?

Did the other shrimp that died have any pitting in its shell? Brown spot or Rust disease eats away at the shell creating little pits like holes.

No it didn’t, it just had some brown spot on it (like the one in the picture).

also I just tested my water- 

ammonia: 0

nitrate: 0

nitrite: 0

ph: 6.5 

temperature: 80F

I'm not much good with disease as i have never had any but 80F is a bit high, I keep mine at 22C though it creeps up on occasions when weather gets too hot.

I had my heater stick on and the attached shows a picture of a dead shrimp which they all looked like, when the other one died did it go like this?

No, the shrimp had normal coloration (apart from the brown spot) and seemed to be active and healthy right up until it died. The temperature has been fluctuating for the last few weeks as the weather here has been 102F and then gets cold at night. This morning the temperature in the tank was like 72F, but will usually hit 80F by the end of the day. I have three Taiwan Bees in a 5gallon tank.

@Fry4friends

the shrimp pictured certainly doesn't look right. 

Have you read the Diseases and Diagnotics thread in Shrimp Health and Care forum?

 

There are two know cures for brown spot.

Levimiasole HCL and Carvacrol oil (oregano oil).

Of the two I would try Carvacrol oil first, as it's easier to find. You can get them in health food stores. Where are you located?

Follow the directions in the Diseases and Diagnotics thread.

 

Even if we have misdiagnosed the issue, Carvacrol will have not harm the tank.

update: after work I went and bought the oregano oil, came home and all the shrimp in the tank are dead. 

Crazy enough it turns out some babies hatched today too. So now I have a tank of newborn shrimp.

sorry to hear that.

If you haven't disposed of the shrimp, could you take a photo of it close up, out of the water? We might be able to use it to ID future brown spot diseases if we have a good quality picture.

 

You might want to continue with the oregano oil treatment, but maybe at half dose but double the timeframe.

Sorry to hear you lost the shrimps, fingers crossed that those babies survive and you can start a new colony!

It still makes me nervous the temperatures though as I have lost a whole tank full at not much more than your temperature and the 'recommended' range is 21-24C?

Hopefully the oregano JayC recommends will sort you out but keep a close eye on the temperature as well!

Thank you everyone for all your help and support ? I moved the babies to a new tank, and took down the 5gallon that they were all in. Is there any way to “disinfect” the live plants in the aquarium and reuse them? Or do I have to just throw them away and start over? I was thinking of setting up a 10gallon for more shrimp, would it be possible to use the same rocks, plants, substrate if I clean them? 

I have also attached pictures of the little guys, hopefully this will help others with the same problem catch it in time.

      Tank Reset - What soil does everyone use?

      By herrwibi · Posted

      I've attached a small bit to the rock as the tank is currently cycling that had the crystal reds in it . I've always been torn between blue bolts and shadow pandas but blue bolts always wins. I never thought about taking some from my other tank and using them a tester but that is a good plan, saves me getting some blue bolts and then all of a sudden i have a big issue again. Hopefully not . That's why i am glad i have the bigger tank and also any of the lighter blue bolts can go into the bigger tank for culling. I've attached a few more favourite. My favourite shrimp which i think this is correct is an extreme bkk . I've also got a photo of one of my many red wines.  https://ibb.co/BVhDMMK https://ibb.co/42Q3ZYc https://ibb.co/gTD403T

      It may be worth holding off on the subwassertang as when you set up the new tank you can then use it in there? I think I could see a few red wine, if they aren't full size, could just have been the light though! There are 3 half size white shrimp with a red head between the large crs in the third photo of the sponge (about half way down), they are beautiful also .They may just be crs but the photo looks redder than those, but may again just be the light! My overall favourites are blue bolts also. I would use some of the crs though for about 3 months as a tester before getting blue bolts for the re-setup tank, you can then remove the crs. You have lots of the crs and you know they are healthy so it makes sense to use them (free) to 'test' that all is ok first, before getting the blue bolts! It will help mentally also, just think how devastated you would be if for some reason the blue bolts died because there is a problem (you won't know with them whether it was the shrimp or the setup), whereas you would still be upset with the crs dying but not as much - they were free and you have plenty of others in the other tank. If you want blue bolts only in the tank you may well get offspring of other colour/pattern depending on the genes of the parents, but then they can be moved to the other tank. ie Blue bolt mother and blue bolt father may create something not blue bolt, depending on the genes etc.

      Thank you, i enjoy a simple scape although i really need to try and take both sections of subwassertang out for a trim. They have just gone mad.  Things are doing great in this tank, i love my red wines as well bit couldn't find any at the time of taking a photo.  There is but i'm not sure they would breed true, i suppose it could be a project for me to breed them true but wouldn't know where to start. My other project i was thinking is just blue bolts in that tank , i love the colour.  I also suffer from slow breeding in winter although i've never had so much success with my taiwans/mischling that i hope it continues.

      That is a fabulous tank, is it built into a wall or partition. Love the simplicity of the layout, you can see lots of shrimp - I tend to overcrowd mine with plants so don't get to see so many shrimp. Great to hear that this tank is doing well and you have quite a few shrimp in there! Especially like the panda and blue bolt in the photos. As you have so many crs in this tank you shouldn't need to buy any more for your reset tank so that will be great and you know the shrimp are good quality and healthy, and that will make a bit of room in this tank for the next generation at the same time? You may experience the slowing down or stopping breeding for winter, though not everyone has that? Thanks for the photos!
