A YouTube channel does that too with other incompatible fish. They even put a betta with the two of them.Hi and welcome to the forum
It's an African Rift Lake cichlid from Lake Malawi. An orange zebra (Mbuna), no idea of the scientific name but they are agro and need hard water with a high pH (GH 300ppm, pH 7.6-8.0). It should not be kept with the elephant nose or anything except other Rift Lake cichlids because they are angry angry fish.
