Sorry for reviving this old thread. I just saw one of my female CRS having the same problem as the Sakura. There is a gap between the head and body, this is the first time I have seen this. It happened to one of my females. I am not sure if it is molting. It has moving around. I think she gave birth last week, her abodmen looks empty. A lot of males are chasing after her after 10% wc. Can someone pls advise.

NO3 - 5mg.
Temp - 22 deg.
KH - 5

i'm using mineral Plus too quite a good effect i noticed is
that once you dose my shrimp will mostly start to molt
and you can see the molted shell the next few hours or next day

I dun have the test kit for GH. My PH is between 6 to 6.5.

Sadly, the female CRS passed away at 1720 hrs. A molted shell was found near her. Not sure what was the problem. It very big and about 16 months to 18 months old. What could be the cause? What is the ideal GH for CRS? Gonna buy a test kit tomorrow.

IF im not wrong..

Gh should be around the range of 3-6.

If the ph is high, GH must be low.

If ph is low, GH must be high

Ph high and GH high is a recipe for disaster.

An example. on the instructions of mosura mineral plus

amounts to use
For tank water ph 6.3 or lower, use 1.5ml for 5 liters of water
For tank water ph 6.3 to 6.8 use 1 ml for 5 liters of water

So i would suppose that anything above 6.8 CANNOT put mineral plus.

My theory is that, acid "eats" away at their shell.. regardless chitin shell or not.. so if ph is high than 6.8, the water is considered quite neutral.

i dunno if my theory is right... but i use this to explain to myself why not to be careless.

That should be about their life span.

Sorry to hear that but i think its a natural death like what cheef said.
if its only happening to 1 dun wry but if it is happening to many u have to worry liao.
1 question Fishy bro u are not using any liquid calcium are u?

To Correct Ning.
Mine wasnt a GH problem, mine was more of a calcium problem to be exact.
High Gh shouldnt be much of a problem for CRS but if it contains alot of calcium, it will make it hard to molt causing death like what silane bro told me.
