Lost 2 more

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%.

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......

And now for some reason I’m seeing 40-50 nitrate in my neo tank that is thriving except for 4 deaths yesterday doing water change now.

I feed this tank that has 100 or so neos of various ages very small amount of bacter EA

and a small amount of shrimp baby powder food from same mfg. 

and in 2 feeding dishes I put one stick of either shrimp party or shrimp protein from company called shrimpy business.

small amount meaning enough to cover the handle end of the spoon that comes with the jar

Unfortunately, you are probably still seeing the affects of the ammonia, 2-3 weeks after.

Nothing much we can do now except to ride it out and ensure the tank continues to be free of ammonia.

Do you feed this amount everyday?

Maybe try feeding every 2nd day.

Sorry to hear you are stillhaving problems but I think you need to accept all the taiwan bees in the problem tank will die off, though you must onnly have a couple left anyway?

Of more cocern at this point is that you now have a problem with the neocaridina tank. I use bacter AE twice a week, sparingly and would feed the baby shrimp food every 2nd day as JayC states and again, don't over-dose. I hope that you haven't lost any more of the neocaridina in the past few days. There is something wrong though if you are getting such nitrate readings!

Yes I feed this every day. I just did a 25 percent water change. 
I will change the feeding to every other day. When I feed the neos that amount daily the food is eaten immediately. And nothing is left .

but in either of the cardinia tanks they don’t touch the food ever.

I don't think the plants are toxic as such, but are they new and if so did you get them from somewhere trustworthy to not have used pesticide etc. Did the shrimp come from your other TB tank, or did yo get some more recently?

Does the tank on the windowledge have a cover on it. I suspect it may be poisoning of some type to lose that many in one day? Always clean your hands before putting them in the tank? Are ANY aerosols/cleaning products (fly killer, hairspray) used anywhere near the window? Can polution come through the window when opened as you are in a city (I doubt you open them this time of year though)? As above, have you added anything new which may have had chemicals on it? Also the same goes for the RO water stored in jugs?

The only other thing I can think of is the positioning of the tank. I think you added a heater to the tank shouldn't get too cold but does the window get full sun and that heats the tank during the day?

Those parameters look fine!

Sorry to hear you are still having issues, it looked for a while you were sorted! What is you latest routine with this particular tank?

The tank with the deaths is a 20 gallon long not near a window. No heater no chemicals.  Everything has been normal so I haven’t done water changes since it all leveled out.

I use long stainless tongs to go in tank never bare hands.

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony. 
    • sdlTBfanUK
      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
