i dont know what they are. there is about 250+ of these little white spikes that grow all over my rock. I've asked local fish stores and they just say they are little calcium things or whatever but i figured id shoot you guys a message. im sure you guys have seen these little things or at least felt them when picking up your rock and find one stuck in your finger. idk what they are, do you?
