been there done both!
I raised over 30 baby shrimps in a 2.5 gallon betta tank (the one you can put dividers in) I used Netlea soil on the bottom about 1 inch, put a marina I25 filter and a sponge filter (small corner style one) and a very small piece of driftwood (the type that has thin snaky like branches)
I put the berried females in this tank and as each had her babies I returned the females to the main tanks...left the newly hatched babies in the tank. I fed earthworm powder mixed with the tank water and syringed into the tank, usually around the sponge area where most babies eat. I also did the same with gravidas, sometimes I mixed both together.
When the babies were about 1 month old I started to feed them small pieces of algae wafers every 3 days along with the powdered food.
I moved all the CRS hybrids to my planted tank, and the tibees/tiger hybrids to the main 3 ft tank....all have survived and are growing very well.
I also used the breeder box to rais 10 red tiger x tt cross tiger babies...this I found was a bit more challenging, as not as much space for the babies to get around, and a bit awkward having to keep taking the lid off to feed etc (air stone thru the hole made it tight for anything else to fit thru like the syringe for food)
I currently have 1 baby BKK in my breeder box feeding off filter floss from another tank and an IAL leaf. I also feed some earthworm powder to it too (very little) Its surviving and growing and as soon as its more actively moving around the tank, it will be put into the main 4 ft planted tank with its parents.
Both ideas have merit, I was able to keep the PH in the 2.5 gallon stable from the Netlea soil which keeps PH around 6-6.2 The babies all adapted and I never saw any deaths, and counted 30+ babies from 3 different mammas in that time.
I am going to do this again with my BB and Snow white mammas in a week's time as I feel it was easier in the long run.
