my rics have been doing great tonight while doing a coral feeding after lights out I notice a stringy white tubular thing going from one ric to another nearby ric (2 1/2 inches away) and it has the bubble like things that are on the rics some what covering its about 2 to 3 mm in diameter I tried to brush it away but it seems to be stuck to both pretty tightly I also notice the rics its coming from seem to have had explosive growth over the last 2 days I would take a photo but I left my camera at work ...any ideas?
