Have you had success caring for Harlaquin shrimp?

[Edward Smith]

I'm setting up a 18g nano and would like to place a Harlaquin shrimp in it. I have thousands of Astrinia at home but read that the shrimp may or may not eat them, so I'd like a backup plan. I would feed the shrimp other starfish but a 18g nano could become quickly polluted. I thought about raising stars in my sump connected to my 210g display and cutting off legs for food but was afraid this would pollute the 210g. Additionally, even if the shrimp did eat astrinia stars, since they're so small, how many/often would you feed.

Thanks for any feedback
