i Just got my shipment from SWF and the coral banded shrimp had a few extras in it it looks like it had babys. and they dont look like brine shrimp it also looks like it is pushing them under her tail.
Sounds really cool! They probably won't survive unless you have a tank to dedicate to just the CBS however.... and it shouldn't have impellors (which is almost impossible for home aquarists).
If you do have baby shrimp and are going to put them into a seperate tank you can use an aqua clear sponge over the intake tube if you have a hand on back filter. I used this for guppies and it did not suck them up.
