I think your ph is a bit high for high grade CRS, ideal should be around 6.0 - 6.8. GH is too low as well. Should bring it up to 4-6.

Oh dear!! Perhaps too clean?

But my grade A CRS able breed successfully and now I have many baby shrimp. I also dont know y my water parameter able breed.

Hey guys, one of my tanks is very strange. It's a four months old 2ft tank with CRS living in it. Initially there were 10 CRS added to the tank when the tank is almost one and a half month old and there are 9 of them still alive at the moment.

When the tank was close to 2 months old, I put some Fire Yellow in to the tank and none of them last a month.

Last week I tried putting some Red Cherry, like 18 of them, into the tank and there were like 5 - 8 of them died within 2 days... Then I moved the rest of them to another tank immediately...

It seems like that 2ft tank is not able to keep Neocaridina shrimps, I wonder what's going on with my tank...

Has anyone experienced the same problem as mine? How did you overcome that?

I'd really like to keep some beautiful Neocaridina Shrimps with my CRS.

Thank you:D

Bro, how are you!

We need some info about this neocaridina killer tank, PH , GH , TDS ?
Neocaridina can adjust to different parameters readily , just that TDS if too low(below 160) can pose some problem
for them.
Its they died after molt?

I introduce new member 4 tail sss and 2 ss CRS into my Grade A CRS tank at last saturday. But today i saw got 2 new member is die. i dont know what is the reason. The old CRS is still working well and no issue.

I am curious why the new member is die ? i immediately use water test kit to determine need change or not. but it look no need . My NH3/NH4 , No2 and no3 all is 0 and PH is 7.2

Anyone have idea why my new CRS die. please comment.

one thing that i learn..
sometimes it's also important to know the parameter of their previous tank(seller/breeder tank)...
because these "hybrid" shrimp is quite fragile...
the bigger margin their water parameter changed...the more risk of death we will be facing...

p/s:
this also apply to saltwater/reef tank keeping

Agreed with budakdegilz, higher grade CRS S-SSS are probably more sensitive to changes in water parameters than grade A CRS due to selective breeding. Did you check the TDS difference between your seller's tank and your own? How much time did you take to acclimatize them? Using slow drip method? Probably sifu arrow could shed some light.

Stumbled upon a full Caridina species grading chart. Not sure if you guys have seen it before. Pretty interesting.

I'm quite fine, but the Neo shrimps are not

I only have PH and Ammonia tester now, PH is 6.0, Ammonia 0.

I'm sure the TDS should not be lower than 160 since I'm using tap water with Tension Gon anti-chlorine.

Some of them died after molt, some of them just died with no reason.

btw, Im thinking of buying a GH tester, any idea which of the brands out there should I buy? Some of my buddies said the API GH tester is very difficult to differentiate between colors while Sera is better, other said otherwise... So i'm kinda confuse now

I'm using the Sera GH tester and it's quite easy to read. The color will turn from red to green noticeably once the right GH is reached.

Like jirochl , im using sera gh tester as well.

I'm using API. Its easy to tell the color change when you have the tube against a white background

Thanks for the replies
any idea where can I get Sera GH tester online?
How much it usually cost? And what is the price of API GH tester?

Hello Everyone..

I didn't take care of my plants for a year..and didn't apply any fert or what so ever...
just let nature take care of itself...

my marselia and anubias...




my ricca...but...but...no leaves...???




any1 interested with my ricca arrr....

would like to start back the hobby...

looking for more easy plants for shrimps nano tank...

I would like to trade for some mini plants...

Micranthemum umbrosum or
Fisiddens or
Hemianthus Callitrichoides (HC)

Anyone can share regarding when the shrimp is having egg, it is not promise will have a baby shrimp after 1 month ,right ? Why this can happen and how to overcome this problem ?

Is shrimp tank have worm is normal ,I saw some im my gravel and it look like is some sort not belong to panaria type. How I can know that worm is harmfull and how to catch most common worm ?

I am interested to start out with some "easy" shrimps...

can any1 tell me what is the different of...

Caridina cf. babaulti shrimps

Caridina Sp. Malaya shrimps

any1 have experience on breeding such shrimps...

thanks Bro for let go your nice shrimp to me...nice meet with you just now.

I'd recommend you start off with cherry shrimps which are the cheapest shrimps in shrimps hobby, except for ghost shrimps. Then you could try some lower grades of Crystal Red Shrimps if your shrimps addiction getting worse XD
