Very Aggressive. Don’t put them in a tank with your community fish otherwise you can enjoy watching the cichlids kick the shit out of the community fish.
If you plan on buying some, purchase them by a few; 3 or 4 and make sure they come out of the same tank for your first batch. If you decide you want to add more to the tank, make sure you buy cichlids of equal size to what you have currently now, otherwise the ones you have now will attack the shit out of your new ones.
