To intimidate other fish, T. meeki enlarges its opercles (gill-covers), deploying
its brilliant red throat membrane, which has earned it the common name of firemouth
cichlid. Despite its small size, it is actually quite belligerent. The dorsal and
anal fins of the male are more pointed. The female lays up to 1,000 eggs, which
hatch in 48 hours; the fry are free-swimming 4 days later. Size: 10-15 cm.
