Ghost Shrimp Turned White... help!

Recommended Posts


I’ve had the ghost shrimp for at least 3 months. About 2 months ago 4 of the 6 turned white. I’ve been waiting for them to die (assuming muscle necrosis), but they haven’t. One of the white ladies actually berried up a couple weeks ago. The white is definitely in the tail muscle, however parts of the carapace have turned white as well in those most affected  AND now I’m seeing black spots develop. 


I’d love to have a better idea of what’s going on with these little guys and see if I can keep them around a while longer. 


Tank info:

10 gallons, weekly water changes 10-30%, well water, heavily planted. 1ml of Flourish added most weeks. 

Ph 7.2

kh between 180-300 (test strip, master kit is on the way)

gh 300

nitrate & nitrite 0

foods used include: bug bites, crab cuisine, baby brine shrimp, tropical flakes, freeze dried blood worms (not all at once... don’t worry...)

tank mates: endlers, mystery snails, ramshorn snails  


*i just changed up the lighting to 6500k bulbs and the algae is having a hay-day. Prior to the bulb change there was not visible algae in this tank

Wow, they don't even look like ghost shrimps anymore.

Its too late for treatment now. However, it won't hurt to try.

Urak, a member of this forum, shared an Oregano oil treatment (Carvacrol oil). Diluted at 1drop to 4.5ml of water. Then soaked the shrimp food in it and fed to the shrimp. 

Look for oregano oil in your supermarkets.

Take pics along the way for comparison.

Safe for fish directly, but I cannot guarantee it is safe for the beneficial bacteria in your tank and filter media.

Afterall, this is supposed to kill the bacteria that is infecting your shrimp.

Sooooo, treat the patient in a hospital tank :happy:

But if you cannot do that, then you need to weigh up the risks.


<edit> - Oregano oil is probably more likely stocked in health food / vitamin shops.

Where are you from? SKF is very international now, I cannot assume everyone is from Aus anymore.

      Another thing you can do to avoid rescaping: Just take some of the fresh soil and put it in your filter.

      Hopefully the fish has just damaged itself as you say, mine do that sometimes, although the changes in the water will undoubtedly have caused them stress and the water they prefer was the water you started off with? There are sections on this forum dedicated to fish, I used it when I decided to try a Betta and got great advice from JayC and this Betta is doing way better than any I have tried before because of all the different things I did/do this time! https://skfaquatics.com/forum/forums/forum/116-fish-keepers/ Great to hear that the shrimps are doing so well. I think it is natural for the berried shrimp to hide away when they are near to birth as it protects the newly hatched shrimps when they are born, and the babies don't move far when they newly hatched either. There would be little to gain at this stage in getting more shrimps before getting a bigger/new tank, it may even be detrimental? I admit to being lazy sometimes and not topping up the tank between weekly maintenance/water changes (disgraceful really as I keep a 1litre bottle of RO water right next to the tank anyway), in which case I end up taking out 2litres and putting back 3litres at the next change, but need to make an allowance for the fact the TDS will change. When I set up the new Taiwan bee tank I measured the water I put into the tank at the start (assuming the measuring jug is anywhere near accurate) so that is how I know there is 28litres in the 35litre tank - it is a good idea to do this WITH A NEW TANK (but with everything in the tank, heater, filter substrate etc) as it is so much easier to do at that point anyway. I did the same with the Betta tank and that has 20litres in a 25litre tank (the one you were thinking of getting at some point). Without the exact figure to put in the spreadsheet then it won't be 'accurate (can still be used to give you as near an idea as needed though)', especially on a small tank! It works to the digit with mine. Even if you empty the tank and refill it probably won't be that accurate as the soil will have absorbed some water, so best do it first fill of new tank. Your water parameters are looking good and pretty much there now so all else being well you should be able to go back to once a week maintenance/water change. I don't know much about Nitrite/Nitrate as I have never had any readings, apart from the old fish/cherry shrimp tank which has always been 50 nitrate for years, probably because there are too many fish but there has never been a problem in that tank? PURELY AS A GUESS I would think the duckweed may have caused the problem/imbalance, but that is ONLY a guess based on I used it once and swore never again, I use water lettuce now, though that isn't perfect either as the routes grow so quickly that I have to trim those every week, but still a lot easier than duckweed.  Simon

      Thanks JayC, I think it is called a Geode, that was what it was sold as when I bought it in US many years ago though it could be something else? I think it is some sort of meteorite? Hopefully, as you say, now it is removed the PH may start to drop and I have put one in some prepared water to test in a week. I will also just see what happens with prepared water left out for the same period just to see what happens with that. Simon

      Those are very good quality shrimps and photos. Simon
