Have you done a water change recently, did you use tapwater?

Apparently there is high levels of chlorine in Brisbane's water at the moment.

I did a water change after i started losing shrimp.normally do 10 percent water change weekly

why dont you tell us as much as you can so we can try and find the cause?

PH

KH

GH

TDS

Ammonia

nitrite

nitrate

temp

Tank size in ltrs

water used

additives used

new shrimp added

age of tank

substrate

the more you give us the better we can help find the prob :)

and if all else fails, we make sure the tank setup is good and ill send some more to get you going again :)

Yes, ALL information on the tank & it's WP, and the period leading up to the loss(s) is critical, as more often then not, several factors may attribute to these loss(s). Posting these info., will also help other members with their tanks too, as ALL of us have/do experience these episodes. I'm with Dean in assisting forum members with this hobby, and will also contribute shrimps to members who have experience their loss, and share/post their tank & WP details....

Okay these are my current parameters

pH 6

kh 1

gh 7

TDS- Dont know what that is. Don't have a test kit for that

Ammonia 4.0ppm

Nitrite 0ppm

Nitrate 0ppm

Temp: currently 21 but last few days highest i have seen was 24. Have kept the lid open and lights off to keep temperature down

Size tank in litres: 28 litres aquastart 320 with undergravel filtration system. Has a stocking on top of filter to prevent blocking powerhead.

Water used: Tap water

Additives used: Seachem Prime, API quickstart when adding new fish or shrimp and water changes

New shrimp added: No new shrimps added or adults however had many berried CRS and gave birth to some. Last time i counted was 7 but bodies disappeared. Found 2 dead baby shrimps.

Age of tank : roughly over 3 months.

Substrate: Gravel that had nutrients it in for plants

Other: Driftwood with java moss growing and

Tank went haywire after commenced on new shrimp products: Hikari shrimp cuisine and Large indian almond leaves.Prior to commencing these products on 26th November. Tank had parameters ph6, nitrite and ammonia 0ppm. Noticed dead shrimp on 27th and did parameter check and abnormal with ammonia spike.

Hope this give you enough info.

what temps the tank? mine got up above 30 and i lost most of mine over the w.e

Mate I have some Cherries I can give you to get you going again if you haven't got some more already.

I bought a chiller on the w/e after 3 days of putting frozen 2 litre cordial bottles in the tank every 2 hours.

am i reading that right?

I would be doing something about that quick smart.

How long has the tank been set up?

By the looks of it you dont have any filtration happening... you would have nitrate readings at least with ammonia that high...

From my view it looks like the tank hasn't cycled for whatever reason and its only after a couple of shrimp deaths that anything has happened.

Why those shrimp died in the first place I'm not sure, but if you can I would be moving the remaining shrimp to an established tank if avaliable.

In my experiences if there are only a few shrimp (<20) then the bioload is so miniscule that the plants are able to keep up with any ammonia. I have had a filter off for a week and it was all perfect readings, there were fish in there too - the plants just kept up with the waste... I didn't even get a reading when I turned the filter back on without cleaning it and blew a bunch of crap all through the tank the plants still kept up. This was however in a very heavily planted tank.

In a shrimp tank with fewer plants I would imagine the situation to go something along these lines.

The tank never actually 'cycled' the plants just took up the load. (At a pH of 6 the nitrifying capacity of the bacteria is something like 10% of that at 7.5 or so)

The new food has different ingredients and for whatever reason is 'richer' and therefore the plants aren't able to cope with the increased load. This has caused some shrimp to die which in turn has also boosted the ammonia and it is a slippery slope from there.

Can anyone tell that i have been watching too many Sherlock Holmes related TV shows lately - Too many theories and speculation :)

Which may be wrong...

Yes you are reading this right. I have been doing water changes to get the ammonia down. Has my tank lost its good bacteria?? My tank has been running for over 3 months. I only have 6 crs left now i think. Ive lost count

:( but so far so good havent lost anymore but tank still haywire. Thank goodness i still have a berried female.

I was thinking of adding frog bit in my tank. Looks pretty cool. Anyone used frog bit in their shrimp tank before.

      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.

      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!
