Jojoe, good to see your post. Hope you can help us out with CRS.

Guys, just want to introduce jojoe to you. Jojoe have a lot of experience with this shrimp compared to us. He is from Singapore and bred these shrimps. I was at his place and he is into the higher grades already.

I think order of importance/difficulty is like this:-
1) we have to keep them alive,
2) then breed them
3) then let's talk about grades and keeping the grade stable. (of course we can dream about it first).

I think (3) is hard to do because grade do detriorate in not good conditions. I have a few friends who can do (1) and (2) but their grade B become grade C after some time and grade C become grade D.

I think I am at (1) only and struggling. Sigh.
