I left my fish for the weekend. I was gone for about 2 1/2 days, which I've done before with no problem. I made sure that all tanks had nice fresh water, the fish were fed, etc etc
When I came back however... it was a house of horrors. Mo's fins look as though they are absolutely disintegrating away, and he's covered in what is clearly ich. I thought he was dead, but he's still barely alive. I couldn't get him to eat, though I've put meds in his tank. I don't know what to do. Is it even humane to try to do anything for him any more?
As if that weren't enough, one of my corys in a separate 10g tank was dead when I got here... with absolutely no explanation for what happened. I don't know what to do for that tank. I looked at the water params and they seemed normal. None of the other fish seem to be ailing.
The only tank without a death or sickness is Jack's. >_< Am I a fish killer? I feel terrible.
