That's what happen for me 20 years ago. When i start to interested in fish. We had a pond with arapaima, and gourami. I jump in and swam with them.I've never had one of my 4 boys try to get into the tank, but I do have latches on it to keep the arowanas from jumping out. My 1 year old put the TV remote in the sump the other day and then started pulling all the K1 media out and throwing it on the floor. The remote still worked too. It was in there for less than a minute. Now my 1 yr old shakes his head from side to side and says"No, no, no, no,no,no, no"
