Yellow Watchman with a hole in it's side!

My goby isn't doing very well today. He hasn't really eaten since I put him into quarantine, and he isn't swimming well anymore. He's kind of crawling around the bottom of the tank, it's hard to describe, but it's not a healthy looking movement. He doesn't look alert today anymore either, kind of dopey. Is this the drug maybe? I'm currently treating with Neoplex.

Here's a photo from this afternoon:



I appologize for the poor quality of the photo, my quarantine tank doesn't have very good lighting.
