Return the starfish to the LFS for a credit and buy some food or something.
Lose the LFS and get a recommendation for a responsible, knowledgeable LFS from someone on this board.
What critters are you feeding?
In a new tank, there is not sufficient food in the sandbed to be able to allow jawfish, stars cukes and others to survive.
Similarly, there would not be enough pods to allow fish like mandarin to survive.
And, an aged aquarium is necessary to have some SPS like acros to survive.
As the tank matures lots of minute food develops.
