You can probably find a few
Alocasia that are suitable enough, although some are not really associated with wet areas in nature and might not make it in a riparium. I understand that there are more species among
Colocasia and
Xanthosoma that grow well in wet soil--a number of them are popular pond plants.
I have done alright with "African mask"
Alocasia by planting it such that the tuber is a bit above the waterline.
I got pretty good root development from that plant.
