Can you keep hatchet fish and firemouth chiclids in the same tank?

Keeping hatchet fish and firemouth cichlids in the same tank is generally not advisable. Hatchet fish are peaceful, schooling species that prefer calm waters, while firemouth cichlids can be territorial and aggressive, especially during breeding. The size difference and behavioral contrasts can lead to stress and potential harm for the hatchet fish. If you wish to keep them together, ensure a large tank with plenty of hiding spots and monitor their interactions closely.
