The daphnia moina cultures are not hard to keep. Depending on the container you are keeping them in, you may be doing a lot or very little maintenance.
I keep 2 2g cultures going, each of them must have ~400 individuals in them. I'd probably ask 10 for 75-100 with replacement guarantee for 2 weeks.
