I found more info over at
About.com.
I can now pretty much trace where it came from. It would be my own fault. Yesterday he didn't have it as I stated before but when I moved him, I likely did iit when I netted him from bag I put in and then moved him into my main tank.
The
LFS I deal with suggested I use something called Triple Sulfa. An anti-bacterial med. Neither Petco or Petsmart sell it. It looks like I'll have to wait until tomorrow to get it and start treating it.
The good news is that in most cases, they survive it without loss of sight. Once that all fixed up, I'll introduce the other clown fish into the main tank.
