Bamboo shrimp will just sit in the outflow and filter stuff out of the water. They'll eat flakes and at night they will sometimes go around the bottom using their fans to pick stuff off the substrate.
I have also been wooking for info on bamboo shrimp breeding and I found it a couple weeks ago because no one here knows how.
They breed basically exactly like amano shrimp (if you've bred those before). You will see them with eggs in FW
tanks occasionally, but the eggs will never hatch. Like amanos, you have to move the shrimp with eggs to a brackish environment for the eggs to hatch (that is the only way, but even then it is still hard).
Same thing goes for vampire shrimp.
I just got cherry shrimp and I'm hoping to have a large colony.
I believe the lighter colored ones are females... so if you remove them all, you'll be having a gay ole time in your tank!
