Disappearing fish.

[Canadoc]

Huh. Well, thanks for the input.
I'm pretty sure my fish aren't just randomly dying, I've never had a problem with water chemistry.... and the other fish are completely healthy. Even the clown was perfectly happy and eating, and then I just found him dead the next morning. The others just vanish, but right up to that point are active, and eating. Hrmphh.

Once again I am left to ponder the mysteries of nature.
