CRS dropped eggs

Hey Mustafa

This morning I found 3 clusters of CRS eggs ... but I only saw 1 female with no eggs ... any idea why this happens?

The rest of the female shirmps are still holding their eggs. The Japonicas were eating the dropped eggs though.

Cheers

Hey Marge,

I have no idea why this happens. I have *never* observed clusters of eggs lying around in my tanks and I have never heard about it elsewhere either. The only shrimp that drop eggs in my tanks are the Crystal Red Shrimp....and they only drop one by one..not whole clusters.

Again...are you sure those are shrimp eggs? What are your water parameters? If your PH is too low, it might be the problem. Red Cherries like higher PH (as opposed to other shrimp). If the PH goes too much below neutral the Red Cherries will show stress one way or another.

I think she is talking about Crystals.

Hi Brad,

I know that CRS usually stands for Crystal Reds, but I know for a fact she does not have crystal reds.

Marge...I guess you could use RCS for Red Cherry Shrimp if don't feel like spelling it out all the time.

Yet another reason common names are evil.

You can say *that* out loud. Unfortunately, with shrimp that are not yet scientfically described or identified, we have no other choice.

Hey Mustafa

Yes, they are shrimp eggs, and yes they are RCS ... sorry ... wrong placement of alphabets ...

I watched her drop her cluster of eggs (have only observed this once when one of the female Japonicas did the same thing as well but she carried the next cluster of eggs to full term - go figure).

I will double check on the ph then. Thanks

I really wish though ...

Well here they are

PH - 7.4
NH3 - 0
PO4 - 0.25 (I am hoping that it is not going through a mini-cycle

)
NO3 - 5
NO2 - 0
KH - 50
GH - 80
74 deg F / 23 deg C

Cheers

Hi Amber!

I'm not the expert, but your params look spot on to me. And .25 PO4 is exactly what you want for a planted tank.

Any chance the eggs didn't get fertilized, and that's why she dropped them?

Hi Amanda

Long time no see girl ...

The boys have been very busy indeed, I counted 6 in their last marathon around the tank ... hehehahahaha .....

But the girls (bright red as they are) are very good at hiding among the java moss on the drift wood ... so maybe, it didn't get fertilized ... I dunno.

How are yours doing? Any latest development on your babies yet?

Cheers

Mustafa..and everyone,
I got a question since Mustafa mentioned about PH. I am quite curious about what the PH will do to different shrimp species. I have PH around 7.1 in my tank, and my cherry red seems doing much better than India green in population growth. Is it normal in your opinion?
And the weird thing is, I have Taiwan blue in my tank as well and they are supposed to hybrid with cherry red(maybe not even called hybrid since they might be the same species) and reproduce normal Taiwan blue. But I still find more and more cherry red young shrimps, the population grows much quickerly than Taiwan blue or India green do.
Do you think the PH plays a role here? Or just cherry red is much more reproductive, even compared to normal Taiwan blue?

Btw, this is Max from San Diego. I am orginally from Taiwan, came to States for graduate school 4 years ago and now working in the pharmaceutical industry.
I have cherry red, India green and Taiwan blue(which we called 'black shell shrimp' back in Taiwan) in my 20G tank with 30+- species of plants, some pencil fish and some tiny corydoras/oto. cats.
My plants(even some Tonina) are doing ok at PH=7+, so I never bother to adjust PH. Although most people recommand PH around 6.8 for planted tanks.
Very nice to meet you folks here, it's always nice to chat with other hobbysts.

When we first got our Reds, the first two females we noticed carrying eggs (about 2 weeks after we received them) both "aborted" leaving little piles of golden eggs on the log. However, after that, they have all been hatching young prolifically. Perhaps the eggs either were not fertile or else they went bad. I've also noticed that shipping sometimes seems to stress the females who were obviously berried during shipping--DOA shrimp we've received via shipping tend to usually be females who were carrying eggs or a female carrying eggs aborted during shipping because the bags had free floating eggs in there. This doesn't happen with every shipment but has happened frequently enough to be mentioned.

KH - 50
GH - 80

Hi amber2461,

Your KH is so high !

I'm breeding cherries but my KH is less than 5 all the time.
I'm just curious how you manage to do it ? Did you add any additives ?

What testkit did you use ? I'm using SERA KH tester.
It is a drop-by-drop test.

To get a KH=50, it is 50 drops. That is half my test solution !
Gosh, what an expensive test.

Cherries are extremely prolific. This is quite normal.
