I'd say the Auratus has been in there for a good 5-6 months, it was an impulse buy while at Petsmart one day. I read they can be super nasty but we've had no problems, just your typical aggression. I think its when theres a female or another male then they became real devils (from what I've read, not my own experience).
Same with my auratus he jus chases my female around with no luck breeding with her lol. I think they get a bad rep in some cases people will mention they have one and every one will so o jus get rid of it rehome it, instead of trying to make it work out.
Auratus are nasty, i used to have an all male in my 10ft tank, he was the smallest one yet he was the boss. One thing for sure, dont put another auratus or he will kill that guy..
