Help! Ghost Shrimp sick with white/blue moldy head?

Recommended Posts

Hey Guys, I'm hoping someone will be able to help me out. I am a first-time shrimp owner. Four days ago I came home to find that one of my poor ghost shrimp ladies has this weird blue/white moldy looking coloration on her head, primarily on her rostum. She is otherwise still moving around, eating normally, and not hiding. I've done some internet sleuthing (I was leaning towards possible vorticella or bacterial infection), but haven't yet found anything that fits the description and was hoping someone may have run into this before.

Tank:
- 5 gallon, long. Fully cycled, 2.5 months old
- Houses 4 ghost shrimp (all female), 1 betta, and approx 9 baby shrimp in a breeding net.
- Filter (sponge) + Heater.

Shrimp have been in the tank with no problem for about a month

Water Params (as of November 8, 2020)
- PH 8.2
- Amm: 0-0.25
- NI: 0
- NA: 5 ppm
- Temp: 78


Treatment so far:
Day 1: 50% WC, and dosed 6ml of 3% hydrogen peroxide (with filter removed).
Day 2: Did the same hydrogen treatment, with no change in the shrimp.
Day 3: Removed all of the plants from tank and dosed 4.5tbsp aquarium salt, with plans to do a PWC later in the week to slowly phase out the salt.
Day 4: 60 second salt dip (ratio of 1tbsp/cup) for all my shrimp and the above hydrogen peroxide treatment. I fear that whatever the white-ness is has spread to at least one other shrimp due to a noticeable color change in her legs and pleopods

Anyone have any idea what this is? I'm not sure if I should quarantine the sick shrimp or just treat the whole tank at this point, as I'm not sure if it's contagious.

Thank you in advance!

Sorry to hear you are having a problem. It isn't something I have seen before but it sounds like you have been doing the right treatments for the suspected problems! From the photo I'm not sure it is either of the suspected diseases.

I would probably just keep an eye on it for now if the shrimp is behaving normally. It may be nothing to worry about or just part of the shrimps usual cycle, getting ready to shed its shell etc, though I am clutching at straws here?

Sorry I can't be more help and I hope it just turns out to be nothing to worry about but let us know if there is any further developments.

I don't think it's Muscular necrosis, which is an internal infection.

Zeragee's shrimp looks like it has an issue externally. 

 

Is the shrimp behaving actively? Eating, swimming, foraging actively?

Or is it lethargic and not moving much?

 

It could be a result of the high pH  -> which means high KH.

Hey Guys! Thanks so much for your replies. It's now Day 6 and the shrimp have shown no change - neither good nor bad. They're still moving, eating, and acting normally.
The only hint that something may be off (minus that white/blue stuff!) is that their red bands have completely faded, and still haven't come back. They also sometimes look a bit wobbly when swimming or falling longer distances. I'll keep up the treatments for at least the next week and will try to find a way to slowly lower the PH in the tank - It's the only thing left that I can see that may be problematic (thanks @jayc)

Thank you to you all for your responses! Hopefully this journey will come out with a happy ending!
Cheers

@zeragee have you noticed your shrimp moulting lately?

I wonder if that shrimp is trying to moult. I zoomed in on the picture you posted, and I don't think it is external. 

Lowering the pH with some RO or rainwater will help soften your water parameters and make moulting easier for the shrimp.

You can give that a try.

I've only found 2 molts in the month that they've been in the tank. All but 1 of them laid eggs as well, not sure if that changes anything.

Two days ago I did a PCW and introduced the new, lower PH water via drip method. The PH is now hovering around 7.9, with another water change coming tomorrow that will hopefully put it closer to 7.6. I also gave the shrimp some blanched kale in hopes of helping build their exoskeleton in case it was external.
But overall, no change. Seems like more of the shrimp are showing symptoms, I may try to up the salt level and I'll keep treating with hydrogen peroxide and hope for the best.
Whatever it is, it's slow moving which may be the one highlight, but I had to see these poor little girls suffer.
Hopefully I'll round the corner at some point soon.


Thanks again for your help!

      Hey guys new to the wonderful world of shrimp keeping, my tank has been cycled for about 3 months now and start of December I got my first shrimpey's! I choose blue jelly's as they are beautiful 🙂 a month in and I have about 3 sets of babys swimming around!! They are all super clear right now getting slightly more blue each day, but there's an odd guy in the bunch..one of the biggest infact is completely see through orange in colour!! No clear no blue but orange..he's got such character and is often doing zoomies around my tank 🙂 but yeh couldn't seem to find any info out there so thought I could consult the community thank you for any opinions on this lovely little oddity
      Struggling to get pic uploaded because of size issues will try update with pics tomorrow

      New to shrimp keeping and trying my best! I think water parameters are OK, have live plants, filter, light on a timer, heater and RO water with weekly water changes and testing. Fed 2x a week 1 ball per shrimp of 'shrimp enhancer ' supplement (calcium and magnesium in etc) but 2 shrimpies have an issue... sort of discoloured/opaque orangey bit on their backs.
      Can't find anything similar in pics so hoping for diagnosis and way to fix please!!
       
      ps. Apologies for crap picture, phone won't focus!

      I purchased this shrimp with a group of amano shrimp... yeah.. pretty sure it's not. Doesn't behave the same as the others, and is huge. Like just under 3 inches from head to tail and its front "legs" are another inch and a quarter long. Any ideal what he is?

      Hey guys, I noticed a couple of days ago that one of my female rocket killies has some sort of disease or injury on her side, and I have no experience with fish diseases at all, so can I get some help with working out what it is and what to do about it? One of my female endlers also has a little white line on the end of her tail, and I just noticed this as well. Please help me with identifying the problems and fixing them.

      Hi ! 
      I live in Seattle where the water is incredibly soft and I have a tap water pH of 6.7, GH of 0-1 and KH 2. My existing tank with plants already has buffered substrate. Would I have better chance of keeping CRS than RCS with my current water parameters ? Or would RCS do okay?    I do have an RO system already, and I could  remineralize my water with salty shrimp KH/GH+. Which would allow my GH and KH parameter to be okay for neocaridinas, but I already have a tank with active substrate. I’m 100% I don’t have space to set up another tank with inert substrate.    Would do you recommend ? What are pH you have successfully kept neocaridinas and have them thriving ?    Thanks ! I appreciate all the help as I am new to the hobby.

      About 3-4 weeks. It depends on your quality of water and the iodine of activated carbon.

      Keep doing this, and feeding it the medicated food. If the shrimp doesn't eat the food within a day, remove it and feed new medicated food again the next day.   You sir, are a good candidate for an RO filter. Your shrimp are not going to like the hard water in the long term.

      The shrimp is in a separate container, but it's been in there for a week or so now. I see it picking off the air stone and the sides of the tub. There is shrimp poop in the container, so it is eating, just not the food I give it. I suck out the detritus and excess food every couple of days and do small water change daily. At first I used tank water, since I don't run R/O. I use a combination of hard tap water with a little water ran through my water softener (I know it's a bit taboo to do). I don't know an exactly how to re-mineralize it to keep the shrimp from going into shock if I used straight clean tap water. I am starting to slowly remove the water from the tub and mixing it with direct tap water with the water softener on by-pass, so hopefully it can acclimate to full clean tap water. With the shrimp feeding, should I try to remove all visible signs of food and fast it for a couple days and then try again?

      Is the shrimp still in the main tank? Or have you moved it into a separate container? There should be no biofilm in a new container, and it should be hungry to want to eat the medicated algae wafer. It won't go away without treatment. The bacteria is not just on the shell (carapace), so moulting won't get rid of the bacteria.

      I've tried to feed the shrimp food soaked in the oregano oil mixture (1 drop of oregano and 5 ml of water since it's 86% carvacrol). The shrimp seems to hate the taste of any food I put in there with the mixture. It goes off and tries to feed on anything but the medicated food. I don't have any other food in the tub and took all the floaters out but seems to be feeding on naturally growing biofilm now.. I'm not sure if I am seeing any results. Should the reddish brown spots go away on it's own or does the shrimp have to molt it off? I've noticed it's been scratching itself a lot.
