I just got my cleaning crew and put them in my aquarium today. I noticed when I received the star fish (blue linckia) the bag it was in had a lot of what looked like brown excrement or insides floating in it. I acclimated the starfish properly, but the starfish has not moved at all since I put it in the tank. I assume it may be dead, but was wondering if they might just be really docile, or if he is definitely dead, he has been in the tank for approximately 5 hours. Thanks!
