Now that several berried females gave birth and my shrimp are thriving in my shrimp only tank, I moved all the adult males and no-berry females to another tank. so my question is; does it pay to segregate the redder males from the clear carapace males for mating with the females, or does it hardly matter.

I dont know I will be able to tell you in a few months. I have stated to slective breed them to find out just that.

Since I have fish in my tank with RCS, and have no other tank avaliable, I just let the eggs hatch in the water and, like Darwin says, "Survival of the fittest". So some of the baby RCS get eaten, but the rest hide and grow up

Spypet,

I wouldn't expect immediate results. After a few generations (3-5) I would expect some results. I think it would take at least that long to get the certain trait you're looking for steady, because as you've said they're one heck of a mix of genes. Starting out with a strict pair or two would work best. Maybe 1 male and 4 females? Limit the males present and select the best females. I've been trying this here and there but lack of tank space has yet to let me see results.

I've read that shrimp uproot HC. Is this true? I was going to convert my feeder guppy tank into nano planted tank with just shrimp, but want to start with emersed HC and dwarf grass.

Hi spypet,

I did that - took out all the relatively weak-colored males and left only one that was redder. My offspring showed a better color pretty soon, so I think that may have paid off. Now some of the ladies are almost concolorous (however only after they were first berried).

efish,
my shrimp leave the HC alone, however, the MTS always dig it out. I've resorted to binding it to little rocks, now it stays in place.

Cheers
Ulli

Default number of offspring

So, I have looked in various places but have yet to see this posted. How many offspring can be expected from one berried female RCS? I know with their minute size it is hard to give a solid count. I am also aware the number probably varies, but I am curious. 15, 30, 50, 70? Also is there generally a high survival rate of all? (shrimp only tank)
I'm excited because, as of this morning, all 4 of my females are now berried! Woohoo!
BTW, This thread is full of wonderful info. thanks to all!

Hi DreamChaser,

you can generally assume that Red Cherry carries around 20 to 40 eggs. Young females have sometimes a little less, one of my very young females had only three eggs (must have been a teenage pregnancy).

The survival rate depends very much on how much food there is available for them. In "sterile" tanks with no muck lying around and virtually no algae growth less will survive than in tanks that look a little unkempt.

Cheers
Ulli

Thanks, Ulli! Haha, teenage pregnancy. I have noticed it looks like 2 of the females are carrying more eggs than the other two. One is carrying significantly less...maybe 8-10?
I have a few oak leaves on top of the Eco, many plants, and <gasp> have allowed algae to grow a bit. The tank has been set since early December, seeded with water, plants, and a filter all from another tank. Hopefully this will provide acceptable conditions for the majority to survive! Even if only 10 survive from each female, that increases my population from 7 to 47! yippie! Thanks again for those who contribute to this thread.
Now, if I could only figure out how to convince my fiance to allow me to upgrade to a larger tank for the shrimp...I could introduce CRS too. hmmm

Thanks for the info.
Do you really need 10 hours of lighting for successful breeding results? Is there an alternative method that's about as good? I'm willingly to do the lighting method if it's the best one, but just curious. :P


Thanks!

Yeah, I was looking on the first page. The guy who started this thread said you needed like 10 hours of lighting for good results (or something like that).

No, it says he personally has 10 hours of lighting which is pretty much irrelevant info...

Oh. Ok. So how much lighting is normal?

I run 10 hours on all my tanks simply to increase growth of bio-film....
