I was looking at my tank today (just a few moments ago) and noticed a strange growth of some sort on a piece of LR. It almost looks as if the rock itself has sneezed and the oozy stuff that seems to be coming from the rock kind of threads out in several directions while the major mass of the glob looks kind of smeared into the crevace of the LR. The major part of the grow is about the size of a pea, only smooshed, and the thread-like pieces off of it are maybe 1 in or less. There are 2 of these spots on this particular LR and a small nodgule that looks like it may be the same thing. What could this be? Good/Bad/ no cause for concern? I can try to get a picture if it doesn't sound familiar to anyone.
