i set the heater myself, it stays at 78-80 degrees, the only thing different in the environment is a little plant she got a week or so ago, real plant not fake. Its actually the same plant that I bought when I got my tank, I remember when I read the directions it said to rinse the plant thoroughly, I'm not sure if she did or not, I will ask. If she didn't, could that be what caused this?
