Thanks for all the support from everyone. "Zag" (aka my fatty) seems relatively ok - well he's always seemed pretty ok considering.I'm sorry about your fish (jjanoch) ~ and my appologies for not saying that sooner. I didn't catch if Phred had also passed?!? Well, mine had gotten so much bigger and had developed that hole looking thing and I knew one on this forum didn't make it, so I was prepared for him to die. I had called my vet (yeah, they laughed a bit) to see if they'd use a syringe, but they only offered to give me one. They did tell me there used to be a "good fish guy" at PetCo - so I called there. No experts I guess, but I asked that guy if he was in pain, and he said probably. I asked about ending it sooner and he said the freezer was the most humane way but that they had drops that would put them to sleep. He said I could bring him the next day as he was just getting off work. I didn't think Zag would make it through the night, but he did and I was just about ready to go to PetCo the next day when we noticed what had happened. He's still not eating - but I'm sure he's quite stressed.
