Red Sea Star

[TRDfan]

I recently got a red sea star from a lfs. Now 3 days later the star does not look too good. One of its arms are turned over (looks like its injured) while the other 4 are latched onto the rock. Is it me or is that normal behavior??

If one of its arm are somehow injured, what can i do?? This is a pic of the star when i got it

I had a red sea star and he always looked the way yours did, limbs wavy over the LR and such.

How old is your tank? Looks fairly new from the pic, maybe not enough food in sand/LR would be my concern
