Forgot to mention....three days ago my Blenny had some clear-ish bristle worm spines sticking out of one side(I THINK that's what they were). They all fell out the next day, but he's been scratching like crazy ever since. Could that be causing all of the itching? The only thing is that he seems to be flashing on both sides, not just the one. What do you guys think?
Possibly. However, since he has been flashing since you acquired him, it is likely some sort of parasite.
