My first batch of CRS. Just arrived yesterday.

Hey, Aquatics International is a great place, and thanks for mentioning it. That's where I got these CRS from.

These are Grade B I believe. I wanted to see if they will do well in my tank, but so far they seem to have adjusted well. Now I'm contemplating getting two SS grade CRS from lelong.

You can check out lelong. There is a shop that provides the stuffs that you need for a shrimp tank. Look under Package.
http://aquashop.lelong.my/

It does not include the tank, pump, lights, or plants or shrimp. But it does tell you what kind of price to expect for the substrate and how to start.

Hi eolith,
Welcome. I'm also looking for CRS SS grade. I know that Aquatics International is in stock for CRS Grade B now. So if you're okay with that, you can try to pay them a visit.
For online, I managed to find on lelong http://www.lelong.com.my/merchant/Aquashop.htm
If anyone knows where to Grade SS CRS is in stock now, please do respond too. I'm in PJ area.
Much appreciated.
Thanks.

You didn't mention whether new or established tank. If new tank, water changes to reduce NO3.
If old tank, the usual WC and you might want to check/wash your filter for decaying matter.

2 months should be okay. I would wash the filter and do a WC to bring down nitrates to below 20ppm.

Careful when washing the filter - use treated water so you don't kill the good bacteria.

Hi waikikizz,
I think you need to do some research into buffering PH. This is very basic for aquarists as the nitrogen cycle.

Your fishes/shrimp will suffer and likely die if PH does up and down. Stability is more important than achieving ideal PH value. Azoo PH down - as arrow said. Don't use that.

Here's a good resource that explains everything:-

Quote:-
Lowering the pH is a more extensive task. If you simply add a product such as “pH Down” this will not work.
Stability is most important.

Didn't know shrimp eat pumpkin. I got pumpkin - I wanna try too. How to feed it? Cook it first? Dry it, or straight from the fridge to the tank?

What other fresh food/vegetables can feed the shrimp?

hehe, we're all learning. I have multiple shrimp food, but its rather expensive. One small bottle between RM40 to RM60+ depending on the type.

Was thinking of supplementing with kangkung from the kitchen so as to reduce costs. I did that a few times - boil a leaf for 2 minutes, then put into the tank. I observe for 5 minutes and see the shrimps were not interested.

Two hours later I come back, I cannot find the leaf. I thought maybe stuck somewhere in the aquarium since its a planted tank. Tried it twice - twice also the leaf was nowhere to be found.

I'm not sure about feeding other fresh food - whether can feed barley, broccoli and so on. And for meat, can cut a small piece of raw fresh prawn (yes the one that you eat) since I see shrimps also eat dead fish or dead prawn (yeah, sometimes they die in the tank). Anyway, just a thought.

Kesian your shrimp. Its eaten alive. Is that Blue Diamond? RM12 to 15 a piece?

I think arrow can advise better, as I'm new to this. For moulting problems, increase water hardness, between 150 TDS and above.
There are also certain foods to feed, but I'm not sure what they are.

Hi arrow,

Why my CRS does not breed? But my cherries breed like crazy? I think if I had to estimate how many cherries including all the babies, I would say easily over 500 tails is a conservative estimate. First batch was only 12 about 6-7 months ago.

4 months ago, I added 12 CRS and 6 Tigers. I lost a few due to jumpers, and 1 CRS died in the tank after I did a big WC. Then I added maybe 6 more CRS/CBS to replenish the losses.

In mid-end December, I saw one Tiger was berried. But its no longer berried now and I never saw the babies. And I've never seen any CRS berried.

Now I think I have left at least 15 CRS/CBS combo and 4 or 5 Tigers.

Any idea why the cherries can breed, but CRS cannot? I understand Tigers are the same category with CRS and will interbreed?

Its a 3 footer tank. Chiller regulated to 25C.
Just measured my PH is 7.0. But maybe it needs to be recalibrated as I'm using ADA soil, so it should be around 6.8.
TDS is 180.
GH is 3-4.

Been sometime since I took readings, but I'm seeing my TDS increase over the past 6 months from 90, to 110, and now 180.

Hi tehoice. 3 weeks is not cycled lol.. Some tanks can even take longer, depending on your filter. Cannot be considered safe for shrimps.
It also depends what kind of shrimps. Yamatos are tough, 3 weeks may be okay. Cherries no. 6 weeks is more like it. CRS are more sensitive.

I experienced cherry deaths at over a month. At first I also thought it was copper, but in the end its due to new tank syndrome..

No, I don't use mineral additives to set GH/TDS. I don't believe in those because last time I used GH/KH+ in my old tank, but it causes shocks during WC. I believe last time I couldn't keep my CRS alive because my water parameters was unstable during the WC period. Also noticed that when I did a 50% WC in my current tank, 1 CRS died the next day. This makes me think CRS needs the water to be stable - rather than ideal.

My tap water TDS is 70. Did a 25% WC today. My TDS was 155 after WC. Then I pumped in the ferts - TDS went up to 165. I pump in ferts every day. Yes, now I will monitor TDS.
Ok, will set temp to 24C.
My ADA soil is about 9 months old now. Not sure how many KGs, but its generally 3 inches thick.

Btw some updates. Just spotted my Tiger shrimp last night. Just discovered she's berried again. hehe.. This means the first batch must have hatched, and the babies must be hiding in the moss, so I don't see them.

Sorry for poor picture quality because this was taken at night. She comes out only when the lights are off, and usually at night. Not sure why she's so shy and I didn't want to use flash. Now I need to start counting the days.

I'm also trying to get rid of this Cyclops in my tank. The fishes cannot reach them because they are in the grass and beneath the rocks. Any advice appreciated.

Anybody want Cyclops? I can give to you if you want to cultivate as fish food. Yes, seriously.

Those are nice shrimps. High grade. May I ask where from and how much?

Hey BB,
When your shrimp is at the front of your tank, try to wave your finger at it. You'll notice it will move its antennae in response to your fingers

Hi arrow,
Are sulawesi difficult to care for? I hear they have different needs from the CRS and will not do well in a tank with CRS due to different water requirements?
Any truth to this? Because I once wanted to add Sulawesi Orchids to my tank but was advised against it.

Thanks. Its a nice shrimp. So sad I can't mix them in my tank.
