Shrimp Dying

Don 78

Recommended Posts

MY adult shrimp have been dying after giving birth.


I only have many baby shrimp.


Water Parameters:


GH  120 ppm  (well water)

KH  120 ppm   (well water)

Ph 7.5

NO 2  0.5

NO 3  2.0


Temperature 73 degrees F.

Standard black and white gravel

Snails-   adults the size of a fingertip

Miniature white spiral snails


Red Sakura

Tangerine Tiger

Gold Yellow

Blue Dream


To my knowledge most babies survive:

Some red

Some red with a prominent red stripe on back similar to Gold Yellow

Some red and clear stripped

Some clear

I had two blue babies that have disappeared.


Planted tank:


Guppie grass

Cryptocoroyne wenditi

Dwarf Onion

Aponogeton Ulvaceus



Sponge filter


Warm white and daylight lighting


No Tropical Fish


Light feeding every other day.  ( I keep the snail population down to the point that they do not compete with shrimp for food.)

Sorry you are losing the adult shrimps.

How long have you had the adults, if they are newish they may not have adapted to the new water if it is quite different from the previous water and the stress of birthing just been too much. Of coarse the shrimp born in the tank shouldn't be affected as they have always been in the water? If this is the problem it will just resolve itself as long as the water parameters are good and steady!

Are those water parameters correct as the KH seems very high at around 6? You shouldn't have nitrite either, though low nitrates isn't a problem.

Mixing different neocaridina will produce low quality offspring so you will get clear and poor colours and you would be best removing any lower grade before they are big enough to breed! The tangerine tigers should be ok as  they are caridina. Young shrimp are difficult to judge what they will look like when they grow, and molt more often than adults, so you don't want to cull them too young!

The adults were in a cycled tank 3 to 5 weeks depending on when they were bought.

Simon has highlighted something that is not right with your water parameters.

You should not be getting detectable nitrites.

The more important parameter to address as a priority is to reduce nitrite, the tank just needs to be cycled properly. You can try supplementing with beneficial bacteria. How big is the tank and the filter? A small tank and filter with lots of shrimp/fish can mean that there is not enough surface area for beneficial bacteria to grow and thus show signs of nitrite build up.

The KH of your water is too high, likely due to the water being well water, which is usually filtered through sand, stone and material that release carbonates. As for reducing KH, you will have to change water sources, to something like rainwater or Reverse Osmosis. Don't use KH down chemicals, which will just introduce a whole different problem.

      Welcome to SKFA. It's a Macrobrachium of some sort. Those claws give it away. But don't know which exact species of Macrobrachium. Might be able to narrow it down to which species if we knew where the shipment was from. Where are you from?   Don't put this fella in a tank with other Neo Caridina or Caridina or Taiwan bee shrimps. It will eat those smaller shrimp.

      Hey all! First of all, thanks for the add!  I really appreciate it!  I hope I am not breaking any rules by posting this in this thread, so if I am, please relocate this post to where it belongs!!  So, about a week or so ago I got a blue crayfish from the local pet store, and they told me that this "Little Dude" (His name!) was sent along with that shipment in error and it wasn't identified, or at least the pet store didn't know what it was, or told me it was another type of crayfish.  After his first molt (Just last night and the fastest to complete one yet) he is a different color, slightly bigger, and I don't think he is a crayfish at all.  I am thinking he is a shrimp, but I am not sure.  If someone could confirm this for me, and possibly even identify what species of shrimp it is, that would be amazing!!  Please don't judge the dirty tank I have been working and then he molted so I haven't had a chance to clean it properly in a little bit.  I appreciate the help!

      Great news that everything seems to have settled down! When you do set up a new folter system, leave the old sponge in the tank for a couple of weeks while new one is running as it will be full of bacteria but the new one won't have any at the start etc!

      It's been awhile but things have been going ok. I got my water parameters back to around where it needs to be. KH back to 4 but I can't seem to increase GH past 5, even if I only add GH remineralizer back during a water change. Anyhow, the tank has been stable. I haven't seen many shrimp deaths or anything alarming. They are still consistently breeding. I do have to feed them much more aggressively, on a daily basis. I also started to add in mulberry and dandelion leaves for them to graze on every few days on top of the other foods. They are a bunch of hungry buggers. I need to swap to a more powerful filtration system than a sponge filter system. While the shrimp poop is awesome for growing my plants, the water has become dank and dark. I'm fine with tannins, but there are way too many particulates in the water. Going to swap to a mini canister filter system with a spin pipe to keep water flow low.. so things are going to get shook up a bit again, but hopefully it all stays stable.

      Simon, Thanks for your input. I will recheck my water parameters. Don
