I got home at 4:00 pm with two sick, grouchy two-year-olds (twins with bad colds).
The first thing I noticed when I walked in the door was that my tank lights and filters were off. With a few minutes investigation, I figured out that our cleaning lady blew an electrical circuit (probably with the vacuum cleaner). I gave her a call and found out that it happened at about 9:00 am, so my fish were without aeration and filtration for seven hours. I tried to be calm as I explained that next time, could she please call me at work if this happens again.
After I got everything back up and running, I noticed that she had cleaned the hoods on my tank with furniture polish (even though I have asked her to leave all cleaning around the tank to me).
Then I noticed that my fish weren't any worse for the wear -- in fact they looked unusually fat and happy. Clementine in particular looked like he had about doubled in size since this morning. They also seemed to be especially busy sorting rocks and poking around the bottom of the tank. Hmmmm...
I figured that I better do a water change to compensate for the lack of filtration. As I was vacuuming gravel I noticed zillions of small (about 1 mm) clear balls coming up the siphon tube. What the heck? Then I noticed that Betsy's vent was even more of an "outie" than it usually is -- it looks slightly swollen and pink.
Then all the pieces came together -- Betsy must have dropped eggs, then the four of them had a heyday gobbling them up all day long.
Now I am just wondering -- could the lights, filter, and aeration being off today have triggered her to drop eggs, or do you suppose it was just a coincidence?
Also, how many days do you think that I should fast them to compensate for the day of gluttony today?
