I recently purchased a used 40 gallon tank from a very nice family and it came with 4 adult male convicts. They have grown up together and are 2 years old. There is a very clear pecking order and the alpha male often chases the others, especially the second largest. They don't bite each other, just chase and flare gills at each other. The two smallest ones show almost no aggression at all and hide most of the time. I'll provide pictures. I'm not sure if they are ok in this setup. Is this stressful for them? They grew up together but they are pretty big now... would you find new homes for them or maybe keep one? I've also looked into new larger decor to provide more hiding places. Would that stop the chasing possibly?
