Male Luvdisc is a kind of amphilophus citrinellus. Female Luvdisc is a kind of cichlasoma synspilum. After a male Luvdisc and a female Luvdisc are put (not putted) in the Pokemon Feed Lot, they may fall in love and thus start to reproduce. Their children are Alomomola(s) which are a kind of 'Amphilophus citrinellus × Cichlasoma synspilum'. Alomomola has all the advantages of Luvdisc. More than that, Alomomola has a larger body size than Luvdisc. It is because a larger size can prevent it from being eaten by any pokemon which is larger than Luvdisc but smaller than Alomomola. This presents the evolution. And thus, Luvdisc is the ancestor of Alomomola.
