I haven't bred them but can give you some generic advice.
Make sure the filter doesn't suck in the babies. I'm sure I read Sulawesi shrimp have a free swimming freshwater larval stage so a normal power filter would suck them in. I would probably use an air powered sponge filter or cover the inlet with tights/stockings to prevent them being sucked into any other filter.
Also keep a steady temperature. Sulawesi like it warm.
I would recomend getting some moss as it gives somewhere for the microscopic food to grow that the babies eat. The youngest CRS I find in my tank are always on my moss covered coconut shell.
planet inverts.com (no space). There very expensive but cool. I heard cardinal shrimp don't have a larval stage but i guess i'll found out in a few months if im lucky. Would marimo balls work for the moss?
their arriving on friday so i got a week
