Sounds like the tank has already been cycled then. If I had to guess they prolly overfed the tank while you were gone and now the tank is having another mini-cycle.
I would be concearned about the Amonia and Nitrite. To get it down I would problably do 25-30% water changes every day for a few days to get those levels down. Your bio filter will help bring them down as well, but both of those can be very toxic for your animals.
