To start with, this is a a bad picture but it's not here to be a work of art, it's here to tell a story.
I've got this aquarium. It has just that one fish in it and a huge ugly algae eater. It was Wade's aquarium. He fed the fish, he cleaned the tank, I did nothing with it. Probably 2 or 3 times a year, he would empty it and totally clean it because it would get that disgusting looking. I can't say for certain but I'm thinking that it was a month or two before he died that he last cleaned this. By now the water should be looking nasty. I haven't done a thing to this. I haven't cleaned it, changed a filter or anything. All I do is throw in some fish food every day and add a little more water when it gets low. The tank is spotless. Like it was just cleaned yesterday, spotless. There isn't even a bit of a algae growing on the fake plants. I am totally baffled. The only explanation I can come up with is that Wade is continuing to take care of it.
