what is going on with my new fish

I try to do weekly changes but must admit that it does not always happen. I also probably am not doing big enough changes. I do 6 gallons when I do changes.
 
Someone correct me if I'm wrong, but the good bacteria adjusts to the bio load. Having only the one fish in there for a month, then adding as many as you did, could have made you have another cycle. There wasn't enough to support the bacteria, then there was too much. Keep doing water changes (daily if needed) and you should be fine in a bit.
