White Sand Star - Bad or Strang signs

[naesco]

Your white sand star was doomed the minute it was removed from the ocean. It very quickly ate all the good stuff in your sandbed and there is nothing left for it an the others critters that depend on the little critters in the sand.
Carefully remove the star and return it to the LFS you bought it from and get a credit and politely let them know that they should not be importing critters that have very litte chance of success in reefers tanks.
