These hybrids have retained the aggressive behavior seen in many Cichlids, like Jack Dempsey fish or their other relatives. They are not very welcoming to foreign species and often get into fights with each other.
Although they are not schooling fish, they still prefer to swim together in pairs – this helps lower their aggression and makes them feel less stressed.
Flowerhorns are an aggressive bunch but with careful planning this can be overcome, and you will be able to enjoy these colorful giants alongside other species.
Due to their bulky body these fish are a bit slow when you compare them to smaller fish.
Just like in their natural habitat, these species prefer to move up and down the water column rather than just stay in a particular layer in the tank.
