I have a group of 5- 1 1/2" to 2". I have already noticed aggression from 1 who is the largest. I did not expect this so soon. I have had adults and dealt with aggression between male and female. They are currently in a 38 gallon with many hiding spots. When one comes in the sight line the chase is on. I wanted to grow this group out and hopefully get a pair. Anyone who has raised a group have any suggestions? At what size do I have to be concerned about one taking another out? Thanks in advance for replies.
