In mid-August, we went on a cruise, and I had my neighbor feed the fish while I was gone. When I got back I noticed that there were many branches in our front yard, and learned that there had been a big storm the day before, which was a day after I had my neighbor feed the fish for the last time. Alas, this rainstorm seemed to have shorted out the electrical source to the pump, and all the fish in the tank were dead, due to no oxygenation. 🙁
Oh well, if it had to happen, it happened at the right time. I had given up on the current round of plants, anyway.
