Totally devastated start to shrimp keeping

Recommended Posts

Zorba

As the title says "totally devastated" !

Over the last few days most of my shrimp have died. Now I know what it feels like and it sucks

From excitement to them arriving my first ever shrimp , several becoming berried , spotting a couple of shrimplets to then seeing them dieing off

I have been doing water changes of around 10 to 20 % every week. I use tap water and let it age and then add  prime, superchlor, and quick atart

I use an inert sand as the substate ,cholla ,and plenty of moss in the tank , no fish. I feed them Boss aquaria Shrimp Crack every 3 days

Originally starting with about 25 blue gene red rillis that Disciple was so kind to send me and now about 8 are left

PH is about 7

Ammonia 0

Nitrite 0

Sorry Disciple for not looking after them , I feel pretty bad

Any idea guys to what I have or not done right?

do you know your TDS?

GH and KH too?

@Zorba

Dont stress man and dont panic. We all have been in this position. Never ever give up, i have gone down to 2 shrimp before and recovered.

Now if you can find out the info jc12 and perps have asked.

Can you think of when the shrimp started to die? Do you remember anything that was done differently during that time? And bug spray being used near the tank? What did the dead shrimp look like?

Take a few pictures of the tank we may be able to see something you missed.

When you do your water change how do you add the water back?

TDS is 213

Temp is 22 C

Nitrate is close to 0

Sorry don't know GH or KH , will have to grab a test kit for that tomorrow

No spray or anything new that I recall , but who knows what goes on when I am at work

When doing water changes I siphon the new water into the tank using 4mm airline hose so it is a slow way 

I just had a thought, I remember a few of them moulting within a few days of getting them. Since I have not seen an exoskeleton, so perhaps they are having troubles moulting. Can they die from this?

I also have a mineral ball in the tank

Yes they can die if they have difficulties molting.

Do you add any minerals when you go your water changes?

i was goig to say maybe molting issue, and bam! you said it

 

i think i had this issue, i got down to 4 shrimp, then started adding minerials and used rainwater and fixed it all

No because I thought you only add minerals if using r/o

I do have Boss mineral balls in the tank

can you add minerals if your TDS already 200+? @Disciple wont it make it to high?

Ok so if you use RO water your remineralise it using a product like Salty Shrimp. Since your tap water is already 200 tds I would not recommend you use this product.

I also use another product called benibachi minerals which are stocked by some of our sponsors which from my understanding add a different set of minerals into the water column which among other things help shrimps with moulting. Boss aquaria also have a product called Mineral powder that does the same thing. It has minimal effects on the tds.

I use it once or twice a week as I believe it replenishes certain minerals the shrimp use up.

I would be very interested to see pictures of your dead shrimp as it would help.

Believe it not I am probably the only person that does not have a smartphone or a decent camera. I tried taking a pic from the rubbish camera I have and it is too blurry

I have Boss mineral powder so I will add some now

I am not going to give up , I just hate them dying from my bad management 

Maybe 2 a day ? I saw some on their sides and then upright and this may have gone on over several hours. The next day they were dead

Was there any discolouration on the shrimp?

Follow the intructions and add a bit of mineral powder. So how it goes.

hey zorba,

im 100% certain you should not be adding quick start and superchlor and prime. the quick start is a bit if a useless product.

especially if your cycle is established (ie no ammonia and nitrites anymore)

and prime is a dechlorinator as well as heavy metal detoxifier so you should not use superchlor as well.

I've no idea if it would suddenly cause die-offs but it's worth considering that if you have been overdoing the prime and superchlor then the sodium tetrasulfate (or whatever it is) and other additives could be accumulating more and more each time you do a WC.

I'm no expert but I am doubtful that you be having so many die-offs in a short period because of moulting issues. Moulting issues will cause gradual casualties..

Unless you are finding dead shrimp that are partially-moulted and died while doing the process then I can't imagine that this would cause so many sudden deaths but again this is just my somewhat noob opinion.

Anyway i do know you should just be adding prime and not using those other 2 products. The superchlor is an inferior duplicate and the quickstart isnt useful at all at this stage.

You might want to do a single large WC and see if that resolves your situation (do it very slowly make sure it is a drip and not a trickle - ie 3+ hours to complete)

love n peace

will

i also think disciples question re discolouration is worth considering!

you could read jayc's wonderful disease/diagnosis sticky thread in the shrimp health subforum and use a magnifying glass if one dies again (hope not!) and check it out for any illness.

love n peace

Zorba,

I have been at stage where no clues at all why shrimps perished a couple times already - hang on mate.

I reckon if one uses RO, most likely all minerals and heavy metals have been adsorbed. Double check the RO water with TDS - you should get 0 reading. I thought both Supachlor and Prime do the same.

I just recently purchase Supachlor (Prime too expensive then I alternative to Supachlor) to dechloronite Purigen. My brief understanding this Supachlor is to dechloronise and take up heavy metals - so not really sure if you need both Supachlor and Prime (since both appear have same function) if you use RO?

Not trying to be a smart guy - I also quite new in shrimp. I reckon a modest feeding would do and not to let the feed stays in the tank too long. Few days ago I fed them snow flake (first time feed them snow flake) and boom didn't realise it would expand. I had to siphon all leftover after 3 hours feeding - a nightmare. Sometimes overfeed can cause ammonia spike.

I reckon good minerals, modest feeding, water change and most important (from many fail experience) shrimps need stable/constant environment. I always like to link shrimp with human in term of breeding - would we want to have offspring in an unfavourable environment such as unstable economic?

I have been doing water changes of around 10 to 20 % every week. I use tap water and let it age and then add  prime, superchlor, and quick atart

Can I ask how many litres 10 - 20% is?

And how much Prime, Supachlor are you dosing?

Overdose of antichlorine can lead to oxygen depletion.

 

 One last question ... how old is this tank since you added livestock?

Thanks for the advise guys , really keeps me going

Jay - normally 10 to 15 litres is the water change

2 drops of Prime per 4 litres , superchlor is a dash

I think tank was running for about 2 months with no livestock

I think your right Will , when doing previous water changes I only used prime. Unfortunately I thought more would be better. Well stupid me has all but wiped out my little friends

Well I at least have 6 left  

.

Was there any discolouration on the shrimp?

No discolouration

Can I ask how many litres 10 - 20% is?

shrimp have been in tank for approx. 45 days

20% water change per week might be too much.

Cut it down to 10% a week.

Add Prime or Supachlor (one or the other, no need for both) to the tap water and let it age a day before adding it to the tank.

Since I have done 1 x 10% water change ,using prime only, and  I have seen 2 perfect moulted exoskeletons and no more deaths

Good news

Thanks for all the help

A recent update

All shrimp have passed away. Still don't know why and I need to work it out before I try again

I recently introduced some mini pellia and some snails were in it. As soon as I noticed them I tried to remove them with long tweezers . Generally as I crushed them a distinct crack was noticeable however snails from this tank had very soft shells. Does that mean the minerals in the water are not high enough? Can this had caused the shrimps to die off?

As previously mentioned I only use tapwater treated with prime

      Hey guys, I’m going away for a few weeks and having a neighbour take care of my tank, as they are already gonna be caring for my cat during that period. I’ll be away for 2 and a half weeks, so not a huge amount of time, but the neighbour doesn’t have any experience with fish or shrimp tank maintenance.
      The tank will be fine without a water change during that time as long as I do one before I leave, I know that, but my 2 main problems are feeding and stopping my intake sponge from clogging up.
      For feeding I was considering getting a couple of pill boxes, like the ones that have seperate compartments for each day of the week, so I can set a certain amount for each day, and which foods.
      But for the intake sponge, I’m pretty stumped. My current intake is a sponge filter connected to the intake pipe, but it’s been clogging up once or twice a week due to how fine it is (and how messy my fish are). When it’s clogged, it puts strain on the canister filter’s motor, and that’s not good. I don’t trust her with cleaning it safely, plus I’m only paying her for 5 mins in the morning, and 5 at night. I’ve considered a mesh intake, but it looks like it could hurt a fish if it went past it quickly... plus I can’t check the size of the inside where the pipe could go as the only one I’ve found would have to be posted.
      Are there easy alternatives that I wouldn’t have to mod, or do intake sponges come in courser versions? (I haven’t checked).
       
      Any input would be appreciated!

      Hey guys, I’m really wanting to get freshwater crabs, and the only ones I’ve found are A. Lacustris and A. Laevis. I can only put them in a 110 L community tank for now, but may have another option in the future. The tank is stocked with a large school of ember tetras, some rocket killies, some endlers, some tangerine tiger shrimp, and a pair of apistogrammas. Rare aqua advised that A. Lacustris would likely be eaten by the apistos, so the obvious choice would be A. Laevis, because they’re larger... right? But I’m worried that they might predate upon my shrimp, so wanted to hear some advice and opinions from more people with experience keeping these crabs.
      Cheers!

      Hi, I've kept Red cherry shrimp for at least 3 years. I've never had a problem with them. I used to keep my shrimp in 500l tank but i got careless while buying plants and introduced planaria into my aquarium. I only noticed after the numbers got out of hand and i noticed the shrimp deaths adding up. I moved 200-300 shrimp into a standard 4ft tank planted aquarium and dosed with noplanaria along with melafix to ward off any bacterial infections. There were multiple dozens of shrimp shells all over after being moved. Initially i believed it may have been the planaria/bacterial/constant water changes/stress of new environment(i drip acclimated them for a 5 hours) that was killing them but i haven't changed the water in a 2 months but i still get the occasional death, 1 or 2 every few days. There are decent amounts of cuttlebone in the filter and also in the aquarium itself, and i also feed them the occasional powdered egg shells but i still get molting problems. Adults and also the month olds are dying, no discrimination. They're fed every other day shrimp snow, high protein discus granules and zucchini/pumpkin/spinach/dry seaweed every 3-4 days. I can see many berried females and small shrimp and also babies but i'm still losing shrimp constantly, easily 80+ in total. I don't want to buy a gh/kh test, they have never had any problems with molting in their last aquarium so can't quite understand why they're having problems now in the 150l. I've read so much online but i can't seem to find an answer, i'd sincerely appreciate any advice i can get. Thank you so much if you've managed to read all of this. Please feel free to ask any questions. The photo is from the current setup they're in.
      Previous tank parameters:
      Ammonia: 0 
      nitrite: 0 
      nitrates: 20ppm
      Ph: 8
      substrate: sand 
      Lighting: generic LED lights i got off ebay
      I don't know any other parameters.  cuttlebone in the tank and filter, no ferts, heavily infested with guppy grass. Large colony of bristlenose. 
      New tank parameters:
      ammonia: 0
      Nitrite: 0
      Nitrates:30-40ppm 
      co2: 3-4 bps 
      Ph: 6.5
      Lighting: generic LED lights i got off ebay
      substrate: ada aquasoil
      The new tank is heavily planted and dosed with root tabs and liquid ferts. Cuttlebone in the tank and filter. 6 large pieces of seiryu stone 17kg (i doubt they're authentic so they're some kind of limestone) Shrimp only tank

      Hi ! 
      I live in Seattle where the water is incredibly soft and I have a tap water pH of 6.7, GH of 0-1 and KH 2. My existing tank with plants already has buffered substrate. Would I have better chance of keeping CRS than RCS with my current water parameters ? Or would RCS do okay?    I do have an RO system already, and I could  remineralize my water with salty shrimp KH/GH+. Which would allow my GH and KH parameter to be okay for neocaridinas, but I already have a tank with active substrate. I’m 100% I don’t have space to set up another tank with inert substrate.    Would do you recommend ? What are pH you have successfully kept neocaridinas and have them thriving ?    Thanks ! I appreciate all the help as I am new to the hobby.

      Those parameters are perfect! I think I experienced the same with the algae on plants when I restarted the caridina shrimp tank, but mine seems to have almost cleared up as well - taken months though. One of my failed attempts with tap water many years ago I had PRL and PBL and it did look much more interesting than just the one colour. They didn't live long enough (maybe 6 months) to really know what the offspring would look like though they will still be red crystal or black crystal  so they should be fine together. If one colour does become more dominant then you can always get some more of the lesser coloured ones anyway in the future.. I did get red babies but no babies lived very long as it was tap water! I would try transferring just some shrimps (may be a third) over to the new tank if you are sure it is cycled and see how they go in a week before transferring the rest over? You won't want too many in the tank anyway if you will be messing about with plants/layout still and you won't loose the whole lot if something does go wrong? Maybe also put the Amanos in the new tank for now so the ones in the old tank won't be fitting with them any more for food? Simon

      Update. I filled the tank, unfortunately, there was some melting of plants and some light hair algae( algae is only on the leaves of some plants, nowhere else?). Adjusted my light schedule and intensity. Things are looking better. Did a 70% water change, remineralized with GH+ powder, and clean tonight. Levels are as follows:   PH: 6.4 Temp: 75 GH: 6-7 KH: 0-1 TDS: 140   Wondering  when I should transfer the shrimps... I want to order 10-20 more CRS, and I’m considering mixing in some CBS. I’m not concerned with selling these, so it would be neat to have two different colors. I know the Black coloration is dominant, but, from what I’ve read, I’ll still get reds from offspring in two-ish generations. Someone said expect 25-30% reds. What do you guys think? My  additional plants haven’t been delivered today, so thats a bummer.

      Nice shrimps, I like that blue bolt in the 7th photo, I want one, I also just purchased today another 8 Red Wine to join my other 3 in the tank, along with one amano shrimps and 23 thai micro crabs.
