Yes, i think they do, beside Mosura Gravidas, i also use BW Vigor and Mosura Eros(rarely cos overdose have adverse effect), but you need time for it to took effect, but other necessary criteria must be meet first especially CRS(water temperature etc) , but if only for RCS then it much easier , i setup one new 1 feet (36l tank, air cooled max 28'c) . dump in 15 selected high red rcs(baby from berried fire red i brought), around 1cm length, feed them Vigor and gravidas as part of the food routine, a mths plus now 4 berried. and another 5 have eggs in the ovaries.
Before that i never have a berried RCS in my first 5 mths rearing them and i have to resort to find/buy berried fire red in LFS(recalling the experience , it was very exciting & chaotic as those berried one normally getting snapped up once stock arrive) so have to take leave just to get it.  phew...
My 5 crs also berried now.

can i know here u all buy ur CRS and RCS??
where is selling cheap? hehe

You try lower your temperature to 24'C, mine last time at 25'c , none of my CRS berried as well and those CRS who was brought berried and giving birth, the CRS shrimplets died after 3 days.
Fire yellow i like, can pm me the breeder you get it from, outside price selling more then normal crs.
Sunkist shrimps..ummm it is like orange or diiferent? , google result showing sunkist like an orange shrimps, you mind take a picture of
your sunkist shrimps and post here for a look?

Have some truth in it cos CO2 will lower water PH, sensitive shrimps like CRS can't tolerate PH swing especially your tank is small and not enough
PH buffer.
That why i remove my CO2 system and convert to shrimps tank.
Oh, remove SAE if have one in your shrimps tank , those sucker is shrimps killer especially when your shrimps just molt. Otto is safe though.

yea which on-line site u buy from? i also searching but much of the seller stop selling now.
is it not the breeding season now?

u selling sakura shrimp??

what is the price u selling? hehe.

Use New Amazonia better , malaya tend to lower PH too much. i'm using New Amazonia in my main tank, PH is 6.4. so far so good ,
CRS, Neocaridina Shrimp all breeding , just discover my golden crs have given birth a week ago , saw a tiny little golden crs at moss(size like a week old).

my new shrimps tank done cycling , took around 8 days. added in moss and floating plant. Not as good looking as L3()nZ

Not feeling well today , goto see doctor , got some free Subwassertang(aka freshwater seaweed) from him beside medicine(paid  ) . 
and some by product tiny apple snail.


Tiny apple snail. need a magnifying glass to verify.

Anyone can inform me if midvalley got fire red shrimp.. Last few weeks i went there there's only crs..

Any lubang to get it?? i'm looking for cheap fire red also but do some of them give you "Sakura Cherry" rather than "Fire Cherry"? "Sakura Cherry" is second grade better than red cherry shrimp and lower than fire cherry right?

mosura can try pm sazuka or get from aquashop in lelong...

mosura got distributor in KL too.. but need to contact them

Acro-Asia Resources (M) Sdn Bhd

sorry , didn't see your post early , so eager want to get shrimps. Where you staying ? subang ? cos you always go NA.

You didn't notice them ... vampire crab, 4 of them.

Paiseh paiseh, instagram effect. The soil is actually darker in color.

Ok.. looking fwd to finding out abt the sample size shrimp food.

Thermos? Without air pump in?? O.o what about from thai enter to msia?

Le()nZ:
does it has the tendency to turned into cherry?
i saw few shrimplets in your picture has transparent part in their belly.
last time i visited another LFS, their fire red shrimplets is full red even few mm length.

arh.... you mean you mixed fire red and "liu li" and cherry in same tank, but they dont crossbreed?
