When I first set up my saltwater tank last year and put in my LR
to cycle with I started finding these little "tubes" of fecal matter collecting in the tank. Every day I would look in the tank and find a new tube. They were all accumulating in the same spot in the tank. Here are pics:
The tubes are very fragile and would disintegrate easily if disturbed. Once I put fish and cleanup crew in the tank, the tubes stopped appearing. This weekend I moved everything in my tank to a new 75g tank and this morning I found one of these tubes again. I haven't seen one in months and suddenly there it was, bigger than before. I suspected some hitchiker from the LR
but never saw anything.
Anyone have any ideas what this is???
