is this something to worry about

[Mmorse]

while admiring my tank I noticed that my gob was secreting something, I dont know if it was coming from the mouth or some where else. I dont know what was going on but I just want to make sure its not going to harm my other inhabitants of the tank. I do know that these corals do excrete waste but does it come in liquid form?

I had one that crapped brown stringy stuff. It is ok. Mine grew so big so fast I had to sell it. I still miss it.
