Exodon's I believe would get to large. Being an active species, adults would need to be kept in an aquarium that is both long and wide. I think the minimum tank size would be a 55 gallon, but what are your dimensions?
Would they eat live roseys also I heated there not that fun to watch because they are stationaryAfrican Butterfly Fish get my vote. They are the small version of Arowanas.
