They are definately a beautiful fish as far as colors they are my favorite. But when it comes to aggression and growth rate they are on the lower side of the scale compared to other aggressive cichlids. They grow really slow, i've had mine for almost a year and he's barely pushing 5.5".....The few that i have owned also got beaten down by smaller JackDempseys and Salvini's....My Salvini damn near ripped the lips off my GT. They lack the teeth and Jaw power that most other aggresive cichlids have. GoodLuck with yours.....
