chocolate chip

I get damaged Chocolate Chip Stars from my LFS to feed my Harlequins. As soon as I put the star in the tank they work together to flip it over and drag it back to their hangout where they devour every last bit of it.

This is my first post so I’m not sure I’m doing it right but I haven’t seen any other posts and I can’t find any answers anywhere... I got a chocolate chip starfish about a month ago and it had been fine until today, it’s brown chocolate chip spikes have turned orange.... does anybody know...
