Mesonauta festivus (Old genus name Cichlasoma)
Unlike other Cichlids, the flag cichlid - sometimes called the festive cichlid,
and not to be confused with the other flag cichlid, Aequidens curviceps - lays its
eggs on vertical surfaces, while the larvae are subsequently attached to another
support by the parents. A temperamental fish: keep it separate from smaller species.
Size: 20 cm.
