Sorry to hear 2 more were lost. Hopefully that will be the last one lost. How many more shrimps do you have in the tank?

 

Nitrate is still moderate to high even after that 25% water change, so that means a lot of ammonia has been converted. 

You might want to do another smaller water change soon. Maybe 10-15%.

Maybe like 6-8 more left 

 

 

I will do 10 percent water change today

I really hope that the tank settles down and the remaining shrimp survive!

I had a very similar experince with my caridina tank earlier this year so I know your frustration. I never got to the bottom of what caused my problem, but in order to maintain my sanity put it down to the diferent substrate. All the parameters are, and always have been ideal and I have tried shrimps in  3 batches all with no success? The whole tank/plants looks very unhealthy, but for now I have fish in the tank and they are doing great. I should probably redo the tank completely with all new substrate etc but am having a break until the fish die off. I will revert to the substrate I used before next time. The only other possible problems that MAY have caused this would have occured due to poisoning, aerosol, dirty hands with cleaning agents or something like that, but I think they are quite unlikely in reality and I've not had a similar problem before in any aquarium? Caridina shrimp are super sensitive and fragile!  

I really hope you managre to sort your problem out before you lose all the remaining shrimp!

2 more deaths both crs 


 

Came home today exact same params so I took 2 sponges from my successful neo tank and squeezed them into the problem cardinia tank and hope this helps...

Picture is from neo tank

The water is stirred up from removing the sponges. It’s usually crystal clear

This is my successful other cardinia tank . Always stable

I never use heaters but it’s getting cold here in New York and these smaller tanks are on a ledge in front of a window so temps were dropping to 68 so I added a heatah

Really pleased to see you have another caridina shrimp tank. Should all fail in the other tank it would be worth redoing that tank (thoroughly clean it and don't reuse anything, that was in that tank before (equipment should be thoroughly cleaned as well), to be sure/safe) and trying again as you will hopefully have lots of spare shrimps from your good tank that you can transfer when the newly reset tank is ready. Bare in mind that it is quite common (I experienced it, even using a heater) that caridina shrimp slow/stop breeding in winter so don't panic if you don't see any/many new caridina shrimplets until next spring?  Neocaridina don't seem to stop breeding any time of the year!

I wonder if it could we something we can't test for such as a bacteria or a virus. Any chance some kind of pathogen could have gotten into your system?

Not sure how it’s an all new set up.

I don’t like heaters as they sometimes fail and cool the tank but I have 5 shrimp tanks in one room and the window ledge is all the room I have left for now for the smaller 6 gallon tanks

A heater sticking on wiped out my wonderful collection of taiwaan bee shrimp, so there is some risk either way. Depending how cold it gets indoors where you live would decide that, but you may be able to get away with not having it switched on most of the time or not really need it at all. Only if it drops below 60 would I think it really necessary! Water changes temperature much slower than the ambient temperature as well so it would have to be really cold indoors before the water dropped to match it! You may not need a heater in Oceanside SoCal I suspect?

No I’m from Oceanside Long Island, new York 

It’s about 45 degrees outside at night sometimes 35 at night so far.

 

So I purchased a ph ammonia and a nitrate meters from Hanna instruments .

still trying to get the ph meter calibrated correctly. 
ammonia still 0 and nitrate still 20 ish 

tds 130

ph 6

gh 4

kh 0

Went away for the weekend and came home to 3 more dead crs ..... I’m gonna puke

Sorry to hear you have lost half the remaining shrimps. At least you have another taiwan bee tank which is doing fine. Be careful not to take anything (including shrimp) from the bad tank and put it in the good tank! It could be an infection as LukeBeveridge above, maybe some shrimp were sick when you got them.

Time to start thinking/preparing to start that tank again! If you are using something different in the tank that you aren't using in any other tank then use what has worked well with the other tanks. At least there is no rush so you can do it at your leisure, and once it is up and running you should have shrimplets you can transfer from your other tank!

There is a device out there to prevent heaters overheating by cutting the power to the heater when it gets too hot, it probably would be worth getting one of those, at least for the taiwan bee tank(s). 

The parameters look fine. The nitrate figue may indicate the tank isn't cycled properly, but I have a tank that has nitrate 25 permanenetly for 5+ years with no problems. You could test the nitrates in the other taiwan bee tank and see what they are out of curiosity, but as I assume you will be re-setting up the bad tank it probably may be better to just get ready to do that.

I feel your disappointment have a tank that is exactly the same and I have (temporarily) given up on that (as I don't know what the problem is) and just have fish in it for now, but I would have to start again if I want to start with taiwan bee shrimp again......

      Good luck with it and hopefully we will hear more along the way. Simon

      Yeah all is well with my tanks. I will be using just the gravel because that's what I'm using in the 5 gal which I plan to upgrade. Yeah I've got a bucket i could put the shrimp in with some of their tank water. And as what jayc has said, I'll be drip acclimating the shrimps because there'll still be some differences from the old tank and the new tank. About the micro crabs, maybe you got something mixed up but I do indeed have some local crabs that I thought of keeping but I'm gonna keep that on the side for now because I plan to try to selectively breed my local Caridinas because some have outstanding looks that I'll try to develop, hence the upgrade.
    • jayc
      A 5gal into a 10gal is double the change in water.  You should drip acclimate. Even more so if it was a move to a 15 gal.   Simon makes some good points with temp differences.

      Good to see you back, I assume all is doing well! As you are transferring everything from one tank to another, and using a neutral substrate (gravel) you can probably do it in one go. If you are getting a new filter as it is a larger tank then I would float the sponge from the new filter in the 5L tank for a week or two to get some bacteria on to it, but it looks like you will be transferring your existing filter which can just be transferred as it is. If you are using some sort of active soil substrate you will need to run that in to avoid any ammonia spikes or other build up of nutrients etc before that is put into the new setup, but you say gravel so this is probably not relevant. I assume you will catch the shrimp and put them somewhere safe whilst you do all the tank work so I would drip acclimate them for a couple of hours to the new water to be safest, once you have completely set up and filled the new tank! If they are neocaridina shrimps you are transferring and the water parameters are very close you would probably be able to miss the drip acclimating, but I would play it safe and drip acclimate though! You will also need to ensure the water temperature is matched when you go to put the shrimp in the tank as the shrimp may have been in water that has cooled over the time they were put to one side. How are the tanks doing, and did the small micro crabs work out? Simon

      Hello everyone, lately I've been thinking of upgrading a tank of mine from a 5 gal into either a 10 or 15 one. So I plan to move all the stuff and shrimp from the 5 gal into the new one. I'll use the same gravel and the same water for the new tank and the filter and plants will come from the 5 gal. My question is, do I still need to cycle it separately with a new seeded filter or is the whole using a mature filter okay? Also is skipping drip acclimation when the water params are almost identical acceptable?
