Breeding shrimp

**chinkha** · 11th May 2005, 16:32

Hello everyone

this is my first posting in this forum.

have tried to breed some cherry red and yamato in my tank.
but most of them wouldnt live until the next morning. 90% of it would be dead by next morning.
even if it manage to cross over the morning, when ever i did a water change around 75%-50% water change they will also dead on the spot.

do you guys have any ideas how to stop this from happening.

could you provide us with some of your tank parameters?? its a little hard to be guessing why they are dying without knowing anything about your setup..

It also need green water type food to survive till 'shrimp' stage. They lay by the hundreds, and fish will eat all of them if u keep any.

If it's your cherry, they give birth. So shouldn't be much of a problem. I however think u change too much water at one time. try change not more than 25% at one time. Just do a more frequent change if it is necessary for you to change 75% water. they lay around 20-30 each time some might not make it but mostly 75% will survive.

For yamato u might want to keep them seperate when they are pregnant or remove the larvae when they are released and put them in brackish/salt water. How much salt is enough... u gotta try.

For cherry once u see tiny shrimplets... try to minimise water change. nothing much to take not unless u have puffers or other fishes.

Hope all these helps

I dont think he has successfully bred any of these shrimps yet..at least not in this tank...read his post again... From what i gather..he is TRYING to breed either or both of them..but they keep dying..That sentence would then imply that the PARENTS keep dying...and not the young....
It wouldn't be too prudent to use 2 subjects in a sentence and not even name one of them..

E.G. JAson and Jim were going to meet.. but he say that he was late..he also say not too late but just a bit..so he say okay...he is late. SO,...who is late? quite silly no?

Hence...what are your water and tank conditions? unless you really did mean your young are dying and teh parents are alive...which i kinda doubt..

Haha, I agree with ranmasatome.

I think he's trying to keep the parents alive 1st.

1stly, why are you doing such a big water change? Shrimps are very sensitive to water conditions and changing such a large amount of water suddenly will surely kill them. You don't really need to change water for shrimp. Just frequent topup will do.

i trying to get the parents to live after one day or more.

for parameter, sorry i don have any test kit to test on it. just started this hobby few months ago. but will get all the necessary test kit in the future.

i did ask the fish shop why this is happening to them. they say somthing about the hardness of the water. so for shrimp, they need soft base or hard base and how to make the water "soft" or hard"

thank you in advance for the help.

Actually...dont need to get ALL the test kits la...its a bit going over board...if you want just get a good pH kit and maybe a KH kit...those 2 would serve you well for your planted as well...

I don't really know whats going on but i can suggest that when you first buy the shrimps dont release them all into your tank at one shot. Leave the plastic bag ontop of your tank for a while..perhaps like 10-20 mins..then open the bag...but dont release them yet... put a bit of your tank water into the bag.. and leave it there again for another 10-20 mins.. repeat this about 2 or 3 times... then at the end of it all release them into the tank. This would help some of the more sensitive shrimp to acclimatise to your water conditions better.. if this doesn't work... perhaps its something in your tank or water that is killing them.. Are there any fishes? and are they okay in the water? Are you injecting a lot of Co2?

thanks for the reply.
ok i will go and hunt for a good PH kit later whem i am off from work.
when ever i bought some shrimp, i will release them all in one go. ok. i will buy some later and release them according to the method you have mentioned. those fishes in my tank are ok when the shrimp are acting up funny. for CO2 i am having around 1 bubble per second for a 3 ft tank.

seen some other article that shrimp are very sensitive, they will be the first one to detect something wrong in the water. is it true ?

I would just like to make a small comment that may or may not be of any relevance

I have only recently bought shrimp, they are illegal here where I live but I did manage to get 13 shrimp from a friend of mine

My water here out of the tap is PH 8.2 and KH 5.5, not sure of my GH but I imagine round about 6. The substrate in my shrimp tank has alot of broken up sea shells that was used to buffer my Tanganyika setup. So as you can see my water ph is quite high + all the shells must be contributing to water hardness in the tank, so far over 1 month I have'nt lost a single shrimp and I now have over 15 tiny babies all over the place. I do not think that shrimp (chrystal, cherry and Amano) are as sensitive to PH as we might think, they appear to acclimate to my high ph with no problems at all.

One thing I have noticed is that they are sensitive to heat and also the water needs to be very rich in oxygen. Make sure that prefilters are cleaned at least once every 2 days as they get clogged and it slows the flowrate of the filter thus decreasing available oxygen in the water. Add an air stone for extra agitation if you have to. I have temp between 22-25 degrees celsius.

Another thing is that you should be sure that any sponges used as prefilters are made for aquaria, try not to use sponges used for bathing as alot of these sponge materials contain Phenols and may be contributing to bad water quality.

These are just my observations so far, I am by no means a shrimp expert, only been keeping shrimp for one month now. Good luck with your next shrimps, I hope they bring you loads of babies

Kindest Regards

Read my previous post...

If you are running co2 thru the night and your shrimps die within a day, my guess is your co2.
