This guy doesn't have a chance.  My other Orange spotted Sleeper Goby hates him and it is pretty clear that only 1 of them is going to survive.  I've learned that if you don't have a mixed sex pair, they are pretty territorial and nasty to each other.
  This one still has a chance to make it, but needs to go to another home ASAP.  He's been moved into my 'fuge.
  If you are not familiar with these fish...it is about 2.5-3" long and needs a decent sand bed to sift through and dig in.
  Here's a reference photo, but this isn't the actual guy I'm giving away.
