New Harlequin Shrimp, Waste issue?

[charlesp123]

Hello I recently introduce a Harlequin Shrimp into my tank and did the whole Coco starfish leg cutting feeding bit for him. I was doing a water change out today an noticed there were some very interesting looking square white colored blocks around where he hangs out and feeds. I couldn't find anything on the internet about what they were. If anyone has any experience with these guys please do tell. I just want to know to remove them if they are waste for nitrates or if they are food leftovers/storage from the starfish leg
Thanks!

You can get rid of them, they are waste.

I never noticed that with mine. Then again he hung out in a cave in the back of the tank. Very cool shrimp! By far my favorite.

Did a little observing and found out that it was part of the starfish leg and was hard as rock
