Hello nice helpful people...
I am cycling up a tank and currently have only live rock and live sand in it (and a few snails, teeny tiny brittle star hitchikers, amphipods, etc.) The problem is that this weird slime bubble thing has suddenly developed (I don't think that it was there yesterday.) It is between two branches of an old coral skeletonish piece of live rock type stuff. It is transparent and irregularly shaped. I would take a photo for you, but seeing as it is clear...
Does anyone have any idea what this could be and how concerned I should be? Please let me know if you have any ideas... Thanks!!! Alice
