Should you keep green terror fish with flowerhorn or can put them discus fish?

Green terror fish (_Andinoacara rivulatus_) are a territorial cichlid from Central and South America. They can be aggressive towards other fish, especially those of similar size or appearance. Green terrors should not be kept with flowerhorn cichlids (_Cichlasoma synspilum_), as they will likely fight and even kill each other.

Flowerhorn cichlids are an artificially bred fish that are known for their large, colorful heads. They are also aggressive and should not be kept with other fish that are not as tough as they are.

Discus fish (_Symphysodon discus_) are peaceful and require warm, soft, acid water conditions. They are not at all compatible with any of the above-mentioned fish.
