Thanks for the input guys I think I didn't specify well enough... The 7ish gallons is just the refugium section in a 30 gallon sump with a 72 gallon main tank. So there is about 90G of water where the Asterinas can multiply safely.
I was thinking that if the shrimp was in the refugium it would have a constant supply of Asterinas coming from the main tank (where they have no predators and are constantly multiplying).
Would the 7G be sufficient space for the shrimp to live? Don't want the little guy to be too confined!
Pat, great idea about contacting the LFS
and using dead stars for food, just wondering whether the shrimp are picky about eating dead stars?
