soon I will have my first group of CRS and now I realize I do not know how to selectively breed them :bs_help:
I was wondering how do you guys do it? I have no idea other than keeping the chosen male and female in a separate tank from the othe shrimps/shrimplets otherwise the better shrimps will breed with the lower grades too lowering the general standard, isn't it so? :huh:

It depends on your stock. If you have a mixture of C and B, group them up.
If you have mixture of C, B and A, group the B and C together and left the A alone. Same theory apply to a mixture of C B A S SS SSS. I have a mixture of ALL type but group them into C B A, S SS SSS. So that A can improve on B and C grades. S SS SSS let them multiply by themself! I always find some A++ in the S group which will be use to transfer over to the mixed group.

General grading is C B A A+ S+ SS SSS G.

Grouping them into male and female is one good way to control and to do selective breeding but you never know if there is oppisite sex mixed in the group. If you feel that they are of the better grades, why not keep them together? Save lots of trouble. :)

They're going to be all A grade, but I read around that part of the offsprings will be lower grade so I thought that maybe it was not bad at all to separate these C/B grade shrimplets from the parents and broters of A grade

Dun worry. You will have plenty of time to move the shrimplet. They took at least 3 months to be pro-active mates. Chances of getting lower grade off spring is 40%. Better grade off spring is 5-10%. Most important thing is to keep them alive when they first arrive. :) Or you already have experience breeding them?

I've got no experience at all with shrimps, but before they arrive here I will to have a good planted tank with Hemianthus, Riccia and cladophlora with CO2 (for the plants and to lower pH) and Hikari pellets:D

watch out for the co2, especially with such expensive speciments.

well, I just wanted to have healthy plants, I didn't want to put it at 100 bubbles per minute ;) above what saturation is CO2 dangerous for the shrimps? I was told they need a bit less oxygen then the fishes as they are crustaceans, is it true?:huh:

I once overdosed a small tank with diy Co2 and the fish weren’t showing any distress but the shrimp were so I think they are as or more sensitive as fish to too much Co2. I have a 20 litre tank with CRS they are breeding fine and I use Co2 (yeast mix) so it should be okay as long as you check your Co2 levels before you get the shrimp.

Grade G ? How does it look like?

Not yet, before I purchase them i want to be sure the water parameter are the right ones and, btw i think it's a little too cold to ship shrimps in these days, so i decided to wait til the weathere gets a little bit hotter

Gold or metallic. Take a look at Silan's gallery. The golden color ones. A rare mutated species of CRS family. If i got 1 i would like to AA aa = Aa Aa Aa Aa then Aa aa to Aa aa aa aa... hehehe

Yeah, this works, you just need 1 Golden CRS. And you can a few in 2 generations. :)
