If you really cared you would be more then welcome to come to east coast and help out with the tanks!! Right now I have a 20gallon tall with approx 200 angelfish fry and the parents just laid more eggs on a filter in a 75gallon with more adult to semi adult angelfish. I will even let you only take care of 5-6 tanks how's that?? Just kidding!!I agree, quitting PT is the right thing to do, and let your knee heal. As I said earlier, you get plenty of exercise around your house and caring for you fish tanks.
