Really?
That is not the information I have on this species and I have done a decent amount of research on them.
There are species that are more communal than others. With larger species, the safest way to keep them is as individuals.
Keeping groups requires a great deal of observation and the ability to recognize when there are problems and the situation should be changed.
I would not recommend keeping animals together unless you have been working with them for a significant amount of time and have a lot of time to devote to observation.
