Dying shrimps

fuzzy stuff appearing on the substrate

Could be a sign the tank is cycling again.

Test for ammonia and now is the time to do more water changes.

If you have another tank/filter, add bacteria from that other tank after a couple of water changes.

Ok. I'm doing water changes, but how does that white stuff disappear? Shrimps are finally starting to act normal again.

Maybe grab a picture of it, just so we don't confuse it for something else.

Great news that you haven't had any more deaths recently, hopefully that is now sorted out!

Many new tanks (mine included) get fuzzy mould looking in them but it usually passes as the tank matures. It usually hapens more with wood in the tank and it is harmless to the inhabitants, just unsightly.  Just leave it a bit longer and see what happens!

I'll give it time and continue with water changes. Today the last of the red wine Caridinas died. All three pandas are alive, and the one that had lost color is going back to normal.

That red shrimp may just have been too weakened by the whole experience to recover. Hopefully the remaining shrimps are strong enough to survive and the tank settles down now! Just let it run for a month and the fuzz should disappear and if the remaining shrimp survive, it may then be time to try a few new shrimps.......

The pictures above certainly look like the tank is cycling again.

Have you got a test kit to test for ammonia, nitrites or nitrates? I think I have asked a couple of times already.

We don't know if your shrimp are now dying because of residual side effects from the disease, OR ammonia poisoning.

At this stage, I'm more inclined to assume the former (ammonia poisoning) with the lack of more information.

Have you got another tank apart from this one pictured above?

I'm sorry I thought I had answered. Ammonia levels were low but o tested today and it was really high. I've kept doing water changes every day but 20-30%. 

I just did a 40% or so. One panda died. Ammonia must be the reason. The 2nd panda is already slow and dying. I don't have another tank sadly.

I just grabbed a cup and added the water I normally use for the shrimps, added salvinia natans and put both pandas left in there. One is dying, the other is still active.

That's really unfortunate, I'm sorry to hear that. What's the exact ammonia reading?

Seems to be 3ppm

Yeah that could definitely be killing the shrimp. Try a slow 25% water change.

No worries.

And yeah, that is the problem with the most recent shrimp deaths ... ammonia.

The fuzz in the tank is a clue that the tank is cycling again.

Well, I have no Caridinas anymore. Blue and bronze neos. I'll keep doing water changes until it goes back to normal. After that, I'll wait a month before trying Caridinas again.

Sorry to hear that, but it will give you the chance to start afresh once the tank has fully cycled, and you have a few neos as an interest in the tank to tide you over in the interim period!

Thank you for all the help. I believe the issue was a bacteria. Deaths have stopped so far. Shrimps are very active, they keep molting and there's still 1 berried female. I keep doing water changes until it cycles, and half the tank doesn't have the fuzzy white thing anymore. The other part does still.

Also, I forgot to say and ask. Very few of my neos are 1 color. Most have a clear area where organs are, then circled by its color. Let me share a picture.

This shrimp seems like it's black but head area is clear. Most of my blue neos were like that.

Now this one is one of the few that grew up 1 colored, and I have no idea what freaking color it is. I didn't buy it, so I'm sure it's one of my first babies from last September/October. But parents were both blue neos, and it doesn't have a clear area where you can see organs. Is that normal?

looks like the antibiotics killed off the filter bacteria.

U should dose something that treats ammonia, like Seachem Prime.

Also add filter bacteria like Seachem Stability.  Or just wait for your own bacteria to come back.

The clear patch on the head isn't something I have ever seen before, it may be to do with the problem you had? Hopefully you will be sorted now but there may still be deaths if the shrimp are weakened. If the black one is the only one with that clear patch I would remove it as it shouldnt look like that, but the blue jelly (and others) in the other picture from the earlier post look fine.

That is one beautiful JADE GREEN shrimp with the racing stripe down the back!

Thank you guys. So exciting to see a jade green shrimp haha. So crazy it came from 2 blue Neos.

Again, tank seems to be back to "normal". I spent a few days without feeding them since there's algae around...but yesterday I dropped half a wafer and they all came like crazy. I took a few more pictures to show you the clear area on the head.

You can usually see through blue jelly shrimp shells so there is a difference between being able to see through the light colour of the shell or seeing through a shell which is clear colourless or even a hole in the shell!

The black on the blues may be part carbon rili colouring, if it is on the shell? From what I can make out from the photos I think it is on the shell and may just be low grade colouring?

Even if the tank seems "normal" again, please be sure to check the ammonia (and nitrite if possible) every day until you are sure the cycle has started again.

Ammonia seems to be at 0ppm or 0.5ppm. Nirites is at 5ppm I think. Sorry I measured all before leaving the house but left my notes at home. I found KH and GH at 0ppm which is very low and TDS at 70. The water I've been using is very soft.

That is low. If your tank is 70TDS, it means your source water is even lower.

It's uncomfortably low for Neocaridina. Can you get your hands on GH+KH remineralisers? Something like Salty Shrimp GH/KH+.

It doesn't have to be the Salty Shrimp brand. Add it to your change water to bring TDS up to 100 initially.

      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.
