Mating behavior was observed on 8 mouth-brooding Malawian cichlid species in aquarium, and was discussed from a viewpoint of the spot type on the male anal fin. The mating behavior for the pair was divided into seven steps; step 1, display; step 2, navigation; step 3, stimulation; step 4, opposition; step 5, egg collection; step 6, fertilization; and step 7, mimic fertilization. Spots on the anal fin were categorized into four types; oval (Labidochromis caeruleus, Melanochromis auratus and Pseudotropheus zebra) , narrow-oval (Aulonocara hansbaenschi) , ellipsoidal (Nimbochromis livingstoni) and disappeared (Aulonocara jacobfreibergi, Fossorochromis rostratus and Placidochromis electro). Steps 1 and 3 was observed for all the species. Step 7 was observed for all the species except forA. hansbaenschi and F. rostratus. Steps 4 to 6 were observed only forN. livingstoni and P. electra. On the other hand, step 2 was observed only forA. hansbaenschi, L. caeruleus and M auratus, belonging to oval to narrow-oval spot types, suggesting the role of oval-type spots in induction of mating behavior of females.
