Is chasing always a sign of aggression?
I originally had three Bolivian rams as part of my 29 gallon community tank. They are going on about three years old now. I unfortunately lost one a few weeks back. I wanted to get another ram but decided on a sunset gourami. He has been in the tank for about 2 weeks now and chases both of my Rams on a regular basis. It does not appear to be overly aggressive but he seems quite bossy and the tank overall even occasionally chasing my neon tetras. The two remaining rams continue their typical behavior with each other but one of them tends to hide more often now. Have I thrown off the hierarchy in the community? Is there anything I need to watch out for? The gourami is beautiful and would hate to have to return him.
Doing the best I can!
