So is the festivum a hybrid?
Uhhhh what? If it has a scientific name, it's not a hybrid...mesonauta festivus
A quick google search is a marvelous thing
All I'm trying to say is use this site for questions that google wont be able to answer, you'll be able to learn much more by inning articles about species you don't know and radiant them, whether you're going to keep them or not. Not trying to be critical, I'm just saying that on questions like that, a google search will yield you an answer much faster
