Indeed. It got me a little crazed in fear. It was like I was fighting zombies with the hammer. It's only a ~30 gallon tank, but trust me... sometimes I miss my old Kole Tang. I think I've had that nightmare. You know, I tried to get a healthy Tuxedo a year or two back. They are hard to get around my neck of the woods. Only one store near me gets them and when they do, they blow out the door. I might pursue this again. Thanks for the reminder. Oh my sorry to hear that. Perhaps you can sell it as fish food for Tangs!
