I have used this set-up for the past 4 or 5 years now with great success…..
5.5 US gallon tank with course black substrate and a large portion of live moss. A small sponge filter set at a very slow bubble, not much water movement. 3 female fish and 1 male in the tank for 5 to 7 days. Breeders are moved directly into another breeder set-up when removed. Within 2 weeks of removing breeders fry are present. Very simple but effective set-up.
This is the same set-up I sent to Frank Reece on the Blue Zoo. http://bluezooradio.com/

…and thats all the filtration you use in 5 gallon breeding tanks?
That’s it! CPD’s originate from shallow still-water ponds. They really don’t care for lots of water movement.
Have fun with your DIY project!

Was it a certain kind of sponge you obtained from Lowes. Or any commercial ones that you find works best?
Would something like this work: http://www.amazon.com/ProPlus%C2%AE-00009-ProPlus-Utility-Sponge/dp/B000CSPRF8/ref=sr_1_8?ie=UTF8&qid=1361929448&sr=8-8&keywords=sponge
No nothing special, just an inexpensive utility sponge with no chemical treatments. Many sponges are now treated with anti-bacterial agents….. not good in the aquarium. This looks like the ones I used to get…..
http://www.lowes.com/pd_109667-962-K-BS9P_4294936624__?productId=1002331&Ntt=spongeI cut them in half and got two filters from each sponge.

At what point would you consider the fry to be big enough to eat the shrimp? 3/4 adult size?
That’s about right, somewhere around 10 to 12 weeks old. They only eat the baby shrimp. I never noticed them being any bother to adult shrimp.

I still use these in small breeder set-ups. You can also get $1 sponges from the home center and cut them in half, just be sure NOT to get the ones that have any anti-bacterial chemicals. This old video show one made using a sponge from Lowes…..

I wrote a short article about this very topic back in 2009…..

I don’t keep dwarf shrimp anymore, but keeping shrimp in grow-out tanks always worked well for me.

I would get rid of the mesh and us a course black gravel substrate. In the wild they are subject to heavy predation from above. That being the case, they try to match their color with that of the substrate, a form of camouflage. Give them plenty of cover either mops or moss and they should do fine.
Dennis
Hi Hank! I generally wait 2 weeks from the time I remove the adults from the breeder set-up. If I don’t see fry by then, it’s a pretty safe bet that there isn’t going to be any. Hope this helps.
Dennis
When ever you have fish that are not very aggressive it can be a challenge to find suitable tank mates for them in a community setting. I have kept them in with other small danios without any problems. I also kept a group with my grand son’s Betta for a time while they were relocating.
He would sometimes herd them around like sheep, but no one was ever harmed and they didn’t behave like they were being harassed.
Dennis
Good luck shift. This is an age-old problem in the hobby and not just with CPD’s.
Keep us posted and let us know what you come up with.Dennis
Yes, you can see them, but they are very small. The eggs you see on the plants are most likely from the snails. CPD eggs are not sticky and fall to the bottom of the tank.
Dennis
in 10 to 12 weeks they will be around 3/4 adult size and sexually mature. That last 1/4 of their adult length often takes a couple more months.
Dennis
I typically move mine from 5.5 gallon tanks into 20 gallon long grow-out tanks when they are 30 days old. If for some reason they need to be moved when they are very young, I catch them using a small cup. Very young fry do not do well being netted.
