I have a neon toadstool. Today I noticed a long thin thread coming from it with a tiny neon piece segmented down the thread periodically, maybe about 4 or five pieces on the thread. It seems almost to be feeling how much room it has around it. It has never done this before. Has anyone seen this on a toadstool?? Look closely on my photos, there’s a tiny clear thread with teeny little neon pieces on it. Swaying around above it. My cleaner shrimp touched it with one of its feelers and it seemed to contract a tiny bit. I feel it wants to check how much room it has to grow.
