I have been noticing that as my groups of reds and yellows have been growing they have started to get agressive with each other.For example one of my two female yellows will grab the other by th side of the neck...the same goes for the reds.My reds and yellows are just reaching breeding age,i have seen the reds mating.So my question is:Is this behavior normal,do the females act like this as they mature?
Thx for looking
