Hi everyone, I put this under stocking questions because I'm having an issue with my 75 gallon right now. It's currently stocked with: 1x blue acara 1x severum 1x blue gourami 2x bolivian rams 7x buenos aires tetras 1x bn pleco Tank has been running for about 5 months now. My severum was always the dominant one until about a week ago. Something changed with my blue acara and now he thinks he can do whatever he wants to whoever he wants in the tank. He will chase my severum around the tank until he hides in a corner behind some plants. If he tries to come out of the corner, he'll just back him down into it. Today I also noticed some tears in my severum's tail fin. The acara will chase the gourami around as well, but he doesn't bully him as bad as the sev. They're each about 4 inches and were put into the tank at the same time. The tank has several different territories and hiding spots, so that shouldn't be an issue. I'm going to bring the acara to my LFS tomorrow to trade in. What are my options to replace him with? I'd prefer another american cichlid because I love their colors and personalities. However, I'm open to other colorful options as well.
