After talking to several people that have successfully housed royal knives together and aros i gave it ago. For about two months my 11 inch and 10 inch black aro did great. Now the knife is bullying the aro. Should i separate them or add in another royal (8 inches in another tank) to spread the aggression. Have talked to many people keeping two royals together with minimal issues
Thank you
