After our jaunt to unexotic lands, I found on our return that I had lost a few fish, one of my reedfish, a rainbow shark, an oranda and two mollys. Needless to say, I was not happy at all, these things are not cheap to buy and the oranda I had had for years. I tested the water and there were no problems apart from quite a bit water evaporation in the sump.
With a heavy heart and a flush of the toilet, they all went to the watery heaven and I took myself off to the aquatic shop to get more fish. I bought a male Siamese fighter, two silver dollars, two shrimps, and two gouramis.
The silver lining to the very ugly death cloud was one of the fish had given birth and there are a few baby fish hiding around the tank, and one managed to make its way through the filter grill into the weir, then took a ride down the pipes into the sump. I thought of moving him to the main tank but decided that he can stay there as he would have a better chance of survival as one of the others would probably eat him. So with the birth of the fish, I can rest assured that the tank levels must be okay.
