So weirdest thing I was looking at my tank and I see something pointy sticking out the middle of the RFA mouth so I grab my tweezers and tap the object and see it’s rock hard. Before I could continue to investigate I get called away from my tank for 2 min and come back and barely see the tip of the object in its mouth. So I was able to get a grip on it and pull it out slowly won’t you know it’s a dang live hermit crab in a cone shape shell it was about a inch in size didn’t damage the RFA to my knowledge it looks fine. It’s just I’ve never seen anything of the sort.
