Cherry Red Shrimp keep dying


KeiraLD

Recommended Posts

I have introduced 12 cherry red shrimp to my aquarium on monday, i introduced them slowly but did not acclimate them like how i have now found out youre supposed to.

 

i have a test kit and ive tested my water, nitrate, nitrite, ammonia are in check, ph is about 6.5-7, Gh is about 13 and kh is a steady 6 drops.

 

ive now lost 5 of the 12 shrimp, in 2 days, i just watched one die, it was on its back struggling, i assumed it was a failed molt, but i left it just incase it freed itself, it died and i scooped it out, ive taken a picture and ill attach it. 
 

every shrimp ive taken out so far seems to be followed by me finding a molt near to where their body was? 
 

is this normal for a new introduction of shrimp, is it because ive shocked them into the water? And are any of my shrimp going to survive or have i set them up for failure? I feel awful

The water parameters are on the high side. GH is way above the recommended range of 4-6.

KH at 6 is also higher than what is should be. somewhere in the 1-3 range is what I aim for.

 

Is this tap water or well water you are using?

The water that im using is from a tap, unfortunately theres no way for me to get water from anywhere else, unless theres a way for me to treat it somehow.

Welcome to the forum!

I believe you are UK based and therefore have hard (lime scale) water. I have just moved from on of the few UK areas which had soft water to an area that is now hard. I have had caridina in the past so already had a water filter so am using those. Depending on the size of  your tank, and whether it is just shrimp etc will depend on what action you may want to take. If you have a smallish tank with just shrimp you could try a water filter jug (brita) which will mean you can use tap water, but the  filters are quite small so may not last very long with such hard water, but may be worth trying with cherry shrimp, this will just filter out SOME of the stuff, NOT ALL, but you probabl won't need to remineralise as it should (hopefully) give water nearer or in the right parameters? Again, if it is a smallish tank with just the shrimp you can go one step further and use a 'zerowater' filter jug (can get on Ocado, Morrisons?, amazon or directly), this has a huge filter and will give you the equivalent of RO water so will then need to be remineralised with GH/KH+. This is the best method but will be a bit more expensive and more work, but will be best for the shrrimps long term. If you have other creatures such as fish in the tank of coarse you will need to think a bit more, as messing around with the water parameters that the other creatures are ok with (?) will likely upset them? If you go the zerowater route you will just replace some of the water with unremineralised water at the start when doing regular water changes and maintenance, or a one time 50% water change, and add the RO water back slowly if the shrimp are in situ . With a brita or similar (as it has some tds/gh/kh etc) you would have to do more of a 100% water change. You basically need to half your current gh and kh numbers. If you are going the best route with RO water and remineralisers you will probably be best also getting a TDS meter, though you may get one with a zerowater jug so check that first?

Not drip acclimating the shrimp over several hours won't have helped either. You should probably expect to lose all the current shrimp, but you may be lucky and have a really tough few, fingers crossed)!

Are you able to collect rain water?

I use this ...

Thanks for the welcome to the forum, and all the useful information.

 

unfortunately i could not get my hands on a zerowater jug right away, but we do have a brita jug in the house, so today i tested the GH of that water, which came to 0? 
 

if i introduce this water to the tank with the high GH, do i still have to re mineralise it, or does adding the 0 GH water dilute the minerals already present. So part 0GH and part Tap water. 
 

but im definitely going to look in to RO water and zerowater jugs, just seeing this as a temp fix while i work on that 🤔

 

yes im hoping i have a hardy few left in the tank as well… 🤞🏼 still seeing 7 alive at the moment

What is the KH though?

No you should not have to remineralise it, since the GH in your tank is already high. Don't mix this 0 GH water with tap water.

The KH of the new water is 4

Those gh  and kh are much better. I would retest the gh though as I wouldn't expect 0 from a brita filter, especially if you still have kh4?

As you noted, the new water (brita filtered only - NO remineraliser

) will dilute the tank, so with a 50% water change you should get around GH6-7 (if the gh of the filteredwater is 0) and kh 5! The new water will need to be added very slowly so as to let the shrimp slowly adapt to it. You can refilter the water again and that may reduce the figures more.

It may also be a good idea to know where you are starting from by testing your Tap water! All filter jugs have a limit in how much they can absorb and so the higher the water parameters are for the tap water the shorter the lifespan of the filter, and brita filters are quite small to start with.

Its good to hear you still have 7 left.

Just to be clear, you don't need RO water AND the zerowater jug, the filtered tapwater will be RO (equivalent) water! You can see on the website etc www.zerowater.co.uk

Don't order/get any remineraiser yet until you have decided how you are going to go forward as if the brita water is gh0 and kh4 then you will only need GH+ (though I don't think the gh0 is right ???), whereas with RO water you will need  GH/KH+. www.pro-shrimp.co.uk are who I use for shrimp stuff and they are very reliable/helpful.

Thank you,

 

im going to slowly remove some of the water from the tank this evening, and drip back in the filtered water once again.

 

i think im going to invest in a zerowater filter, although more expensive than some other methods it seems to be a bit easier. 
 

ill have a look at some remineraliser for the water when i get the zerowater jug. 
 

thanks so much for the advice on different filters and correct levels, its really helping me learn a lot about keeping shrimp. 
 

Still all alive today, fingers crossed for them, im determined to get this right 😊

You can (and should if you can) remove the old water all in one go, that won't alter the parameters, it just depends on whether taking out half the water will affect the filter system or heater etc. It is only when adding the new water that it must be done slowly.

The zerowater may look a bit dearwr but the filter is more than 5 times the size so will last longer.You won't need the GH/KH+ at the start, until you get the parameters to the level you want. Once you get to that stage, as the remineralser is prebalanced tds/gh/kh ideal for the shrimp, so you will only need to use the tds meter when mixing the new water, and occassionaly test gh and kh. The zerowater does take a long time ti filter as the filter is so big, so is only really suited to small(ish) aquariums!

I have my fingers crossed the remaining shrimp are super strong ans survive.

Shrimp usually suffer from shock and stress when they are not given enough time to acclimate to their new home. That is why it is imperative that you do the Drip acclimation which is an important process for aquarists to learn, especially those who want to put shrimp in their tanks. It is considered the most straightforward and safest method of acclimating shrimps.

      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!
