Like I said, I was just speculating based on my limited and decade-old knowledge of organic chemistry.

Hmmm, is this the same tank you recently had fish death in? How often do you feed the 10-12% fat food?

Arrggh! Please don't make me regret going on vacation!

Thanks for stepping up as always, Arlene, you're a superstar!

Since I will be out of town as of this Saturday, I'll need all of you to coordinate the food arrangements in this...

Cool!
