Hi guys. Tried shrimp twice before without much luck, and have some shrimp on the way from aquabid in hopes that the third time will be the charm. I heard that these three species are the easiest ones to keep and that is the main reason I went for them. In the past I kept RCS for about a year and they never did that great but they were in with large fish so no big surprise. There were a few holdouts for some time but eventually they all went the way of the dodo. Next I kept some ghost shrimp in a ten gallon and they were breeding like crazy and doing a great job cleaning up all my filthy plants from the other tanks, but eventually I added in too much plant matter that was too dirty and they all suddenly died off.

This time they are in a 40 gallon all to themselves with a bunch of moss and aquascaping of various kinds so I hope they will do better. This has an aquabridge to a 60 gallon tank with plants and aquascape and a few small fish in it. I will keep the shrimp and crayfish alone in the 40g tank for now at least. Maybe if they take off enough I will add in a few tiny fish like white clouds and so on that won't affect the shrimp much.

I believed my tap water parameters were good for virtually all aquarium needs but in some aquabid auction I saw that any kh above 8 would lead to shrimp being unable to molt and eventually kill them. The ghost shrimp actually bred like mad in the 10g, but the cherry shrimp never really took off even though there were lots of places to hide from the big fish. Is this water hardness a serious problem for those guys? RO water is really not an option because I am on a budget. Possibly I can afford to ameliorate the water with chems a bit if it is a serious problem though.

"19 gh 20 kh 8.3 ph Cherry Shrimp, Cajun Dwarf Cray, Malawa Shrimp"

 

hopefully not all in the same tank with the same water parameters.

Each specie is very different in their need for the right water parameter.

Only the Malawa shrimp, a type of Sulawesi shrimp is made for water with GH19, KH20, pH8.3. The Cajun Dwarf cray might also be okay with that hard water. 

Cherry shrimp will not survive for very long in such hard water. Their eggs wont fertilise and they will find it hard to moult. 

the Cajun Dwarf might a wider range of water parameter requirements, so will fit in RCS water or Sulawesi water.

Ok, maybe I can put them in a different tank I guess. Thanks!

      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.

      I have had a 20 gallon RCS tank for 3 years now.  I have moss balls and some JAVA moss, drift wood, and mineral rocks.
      Only RCS in the tank and some soft shell snails I have in there I breed for my fresh water puffer fish in another tank,.
      My issue is that the shrimp live 1-2 years and they breed just fine but I never see babies.  I see plenty of eggs but never babies.  (Well 1 or 2 a month maybe but they disappear)
      The adults keep going just fine until they die off of old age or something else.
      I keep about 100 shrimp in the tank and have to replenish 50 every 6 months about.
      Water Temp I keep about neutral. 
      PH- 7- 7.2
      I use distilled water or sometimes Reverse Osmosis water because our tap water goes through a water softener which puts a LOT of salt in it which makes TDS very high so I try not to use tap water at all.   
      I feed every 2 days with Azoo or other good food and not much.  Its all gone by the time I feed again.
      I do add some powder food for the babies and a shrimp bacteria powder (just started that about 6 months ago but has not helped or hurt)
      Someone told me due to the distilled water my issue is LOW TDS.  So I bought TWO different meters.  I tested the distilled water and its about zero which is correct.  I then tested my water and its about 700.   I do top offs and just did a 20% water change last weekend with distilled water.
      So is that the issue?  Should I pull out the mineral rocks?
      I am thinking tonight to take about 8 gallons of water and drain the tank down about 40% and then fill with the distilled water.   I can repeat the process in a week and once I get the TDS under 150 I can add a little shrimp mineral to get it to the 200 range.   The reason I am saying that is the TDS could be bad TDS and not the minerals they needs.  I ordered some Salty Shrimp Mineral which I heard was good.
      Should I just give up?

      I bought 7 RCS for my 2.5 gal tank yesterday (no filter/heater). I also have a marimo ball as well as some java moss. I was wondering if this no filter set up is okay for my RCS? This morning they were acting less active than yesterday. They weren't picking at the marimo ball or anything, and were all just standing still..

      Hi Guys,
      Over the last couple of days I have head some RCS deaths. One I am not sure why and the other one I felt like she was going to die as she could not moult (I could see her shell almost split in 2 at the saddle). All females in this tank are breeding exceptionally well and all other shrimp seem fine.
      My water parameters are:-
      6.6ph 0 ammonia 0 nitrites 10 nitrates 200 TDS (a bit high for my liking prefer around 170, so will bring this down slowly)   I keep these RCS with my CRS shrimp.   So I am just wondering if it is my setup that is causing these issues or just coincidence that these two deaths happened at the same time?

      Hah! LOL, how did I know. If I was going to put a bet on one or the other, it would be the rocks from Phillip Island ... from the beach. How to test? do the vinegar test. Take out a bit of gravel, and a small stone. drop some vinegar on them to see if you get a reaction. Alternate test is to put them in a cup of water. Test the water GH and KH before adding, then test again after a few hours to see if KH and GH have increased.

      ahh shoot. gravel was washed about 20 times thru, and rocks were boiled. gravel was sold as aquarium safe gravel, but the rocks were from phillip island, along the beach... how could i just test 1 or 2 to see if that's why? (they're all the same type, but i have a few big ones that r heavy and a bunch of small ones that i can test with)
    • jayc
      That means you have something else in the tank that is leeching carbonates - like a rock, or gravel or shell grit.

      eek! I've been trying to reduce the hardness for a few weeks since i noticed it was high. I'm in melb, and my tap water is relatively soft, but it doesn't seem to make a difference to the hardness when i do water changes. I've been doing up to 40% weekly (on average maybe 30%) but have barely seen improvement... I'm using water that's already at about 23 degrees from tap, would it make a difference if I used just cold? (I've only measured cold tap, not heated as i didn't think it would be different). Otherwise if I could get RO from somewhere would that help? Thanks!

      Those parameters are getting too high for a killi. Killis definitely prefer soft water and slightly acidic, pH under 7.0. Irrespective of what disease it might have, it would be a good idea to start reducing pH, GH and KH slowly now. Where abouts in VIC are you? Melbourne's tap water is generally very good for softwater fish. If we can't ID the disease, start with an all purpose cure, like malachite green.
