I currently have two synspillum, one normal fenestratus, one pink fenestratus, one bifaciatas and one melanura. Except for one 3 year old synspillum, they are all juvenile or sub adult and I haven't found personalily in any of them yet. Vieja species tend to be shy and do not display the boisterous behavior like Midas and Jaguar. I haven't come across a glass banging Vieja fish yet.
