Hi all! I'm new to keeping guppies and looking for advice on some guppy fighting I have going on. Right now I have three male guppies in a 10-gallon tank. They were introduced to the tank a little over a week ago. Two of the guppies get along fine but the third guppy is constantly harassing one of the other guys. I was hoping he'd settle down but after a week with no behavior change I'm not so sure. I'm debating between three options: 1) Give it some more time and see if things improve 2) Return the jerk guppy and try to find a more docile guy to join the gang 3) Return the jerk guppy and stick with the two I have Thoughts?
