Well we did a water change a week and a few days ago, been haveing problems with the tank since. Some how we ended up with some kind of infection in the tank. We didnt realize it till after we had bought more fish to go in the tank and they started dieing. We thought it was just cuz some were feeders and its common. But now even our more established fish are falling over after being healthy. They show no signs of ick and are fine and swimming around then next thing you know they are gone. I did some research and found that its possiable that after the last water change that we got some infection in the tank. Wish had known BEFORE we bought the other new fish but oh well.  We got the tank treating right now so we will see. I am not sure what we are going to do when paul notices as he LOVES his frog and his fish he goes and watches them all the time.
