hi i just saw this pregnant female crs in my tank... and it seems that her eggs are out of her saddle/stomach.. is this normal?
Could she be dropping her eggs...
http://www.aquaticquotient.com/forum...ad.php?t=46576
oh well she kicked the bucket this morning.... so frustrating...
Sorry to hear that.
I'm not sure about CRS (think should be similar?), but other shrimps, when they are about to hatch, you will see 2 black dots in the eggs, still in the mom's saddle. That's what I saw with my green pregnant shrimp this morning...
I guess for crs it's quite hard to see as their eggs are abit hard to see but
yeah i think they change colour when they are about ready to hatch.. they turn lighter in colour... not as red...
however for this case.... she was only recently pregnant.....
i'm really not sure what is wrong with my tank these days... as there are more frequent deaths and the shrimplets that have just hatched from another female have all disappeared after 2 days...
my water parameters are:
PH 6.5 - 6
NH3 0
NO2 0
NO3 20
KH 0
GH 60
values obtained from api 5 in 1 test strips
if anyone can advise... thanks
Hi fishpoo,
The picture shown is female crs dropping eggs. The reasons due to her death or dropping of eggs can be many. Well, to date Im still figuring out the main reason to this as I find its difficult to control the death of young pregnant CRS.(Old ones not counted) So, I can only classified them as superb sensitive. What ill suggest here is minimal feeding as always and try to maintain high dissolved oxygen level in the tank.
May I know when do you usually find their dead bodies? In the morning when you switched on the lights or at night when the light has already switched on?
To measure your ammonia and nitrate levels more accurately, Ill suggest go for those that only measure these two seperate values test kits. Test your ammonia level again and see if its really zero. Remember- try obtaining water from the bottom of the tank and not the surface. Its tricky when doing so. How I do is to use a small siphon to obtain the water.
Cheers.

oh thanks alot for your help spid..... really appreciate it as it's getting quite demoralising at times... seeing pregnant females drop like that... i'm using API solution to test for ammonia.... usually i see deaths in the morning when i on the lights..... what does that mean? not enough oxygen? my tank is moderately planted... have some water wisteria, spiky moss, us fissidens, a bolbitis, and some japanese hairgrass... no CO2 low tech tank here.... once again really appreciate your help
Sure no problem, hope you can learn something from my gibberish.
Plants photosynthesize in the presence of light and respire without light. Without lights on, they will take in oxygen and give out carbon dioxide. Imagine in the day shrimps would have so much O2 but at night they suffer from lower dissolved o2. Hardy shrimps will be able to take the change but not those weaker ones.
Try introduce an airpump, provide aeration in the night and observe whether it works.

oh i see that could explain why one of them actually swims up to the water surface sometimes..... but do you have an air pump in your crs tanks? i'm keeping my tank in my bedroom... so an air pump might be quite noisy for me as the chiller already is quite noisy......however I have experienced about a month of peace... as in no deaths at all and 2 of them getting pregnant... however those that recently hatched have disappeared after 2 days... i have a sponge at my filter inlet... so i'm assuming they wouldn't be sucked into the canister... it's really quite depressing sometimes....
Yes I install airpumps for every tank. Go for eheim air pump if noise is a concern. This peace can be spoilt by increase population or increase feeding that leads to higher ammonia in the tank.

oh are you using ehiem as well? any idea how much it costs? anyway thanks for all the input once again... i think i'll give it a try
oh... learnt something today.
so it is lack of oxygen if i find dead shrimps, if any, in the morning (though not CRS), no air pump. have never found dead shrimps during the day.
Never create what you can't control
It's never a forgone conclusion. Shrimps are generally more delicate than most fishes, so they can be easily affected by low dissolved oxygen, ammonia/nitrite (even low levels can easily cause issues), temperature and so on.Originally Posted by beetroot
hmm went to C328 just now and they do not have the ehiem air pump... they claim it's very noisy and don't carry it..... the uncle doesn't think that air is the problem in my tank.... but he did not offer any solution either...... and lastest update... another death this morning.....
really have no idea what's the problem... i don't think it's the air as they have survived for almost 3 months without an air pump? tested for ammonia again from water near the bottom of the tank and it's 0 still....
i feed once every 2 days but i'll leave the pellet in the tank... as i see them hanging on to the pellet... and 1 of them will usually grab the pellet and run off to hide somewhere munching on it.....
and advise is most appreciated
Maybe can try dose mosura shrimp tonic to boast them up? Also you have old sea mud in your tank? No need to just get ehim brand air pump, maybe you can just try other airpump and see if things improve? Also its best if you can remove any leftover food.
Cheers~
ok have installed the air pump last night.. no deaths that i can see this morning..... yes i use mosura old sea mud... but i just dose into the tank after weekly water change...
as for the food, it's actually quite hard to find.... as one of the shrimps will grab on to it.... and run into hiding....probably under one of my driftwoods...
have not used shrimp tonic... is it necessary?
I feel its not a must but good to have item but so far only saw positive feedbacks(still looking out for negative ones though..)
Anyway, i use it because my shrimps are still new to the tank and since tonic claims to boast their immue system so i was thinking why not.
So far my 8 SS seems ok, today is the 9th day..but having hard time locating them because of the size of my tank and the amout of moss...but will appear once shrimp tonic are dose as they look more active then ever.
another one of the crs is dying... it's on it's back in one of the pictures... sorry for the low quality.. it's my phone camera....
i'm really at a lost as to what to do now.......
funny thing is 3 of my hinos are alive plus a pregnant A grade.... where as the rest of the A grades are dropping one by one....
hopefully some of the bros here can help
Maybe you will want to give a full detail and parameters of your tank(size, filter, how long was this tank setup, water change frequent, water temperature etc). Also your parameters when you discover dying CRS. Im sure some pro can help to see what could be the problem.
All the best~ And also all the best to my shrimps since its only the 9th day...
Remove the rock, remove the bogwood.
Do some water changes.
Dose Bio additive to strengthen the bio capability,these weakened shrimp need good water quality (I am not referring to water parameters) for recovery.
Things will be better for you, but those badly damaged may die off, while the not so bad one will recover.
