Hey im pretty new to reef keeping and I've found a couple things in my tank. One of which is creepy while the other is cool. The cool one looks like big bubbpe algae but its red and part of it glows red in the blue light and the creepy one looks tantacles moving out of a pile of sand, the tentacles are kinda sticky move sand around sometimes. I just wanna know if these things are harmful
