red spot on watchman goby

[rancoo]

There is a red spot right behind his front fin. not sure if this is a disease or if it is maybe that my anemone stung him. The goby was pushed out of his spot by the nem. http://img.tapatalk.com/aeff4397-d980-90ca.jpg

Is it a spot, like a drop of ink... or is it something hanging on the side...

It could be a parasite..
