I have 3 jaguar cichlids in a 5 ft 125G I've had them 3 weeks today. When I got them they was only around 2cm and used to swim around together (I Knew this wouldn't last). There now around the 2/2.5 inch mark and one of them completely owns the tank, I have one hiding behind the filter and another behind the filter return. There's loads of cover in the tank in wood and rocks and artificial plants, I thought i would get them to 4 maybe 5 inch befor I had any real issues. Is this common in other people's experience I knew one would be dominant but this one is next level aggressive compared to the other 2.
