While doing maintenance on my tank today I found these weird tube like things sticking out from a piece of rock. I couldnt see them at first because they were hidden behind some Coraline that I couldnt get to. Anyway, there are about 12 of them about 1/16" in diameter. They appear to be a pale greenish yellow in color. You can actually see the hole at the end of the tube. I tried taking pics but they are so small and real close to the glass and the pics arent coming out, they are all blurred. Any ideas what they could be?
