I bought two maroons at the same time. They were probably about a half inch at the time. They paired up, now one is about three inches and the other is about one and a half inches. It took a couple of months but they paired up and are now hosting a LTA. The larger one is becoming quite aggressive to the other fish in the tank but she gets along fine with the smaller male. I think the maroons are pretty but they are becoming quite aggressive as they are getting older
