a year ago when istarted my tank i had 3 severum juveniles and 3 angels.
the severums beat on the angels and i ended up getting rid of the angels.
hold onto gold severums as they seem to be worth abit in my area. my two at only 6" sold for £30.
if you ask me severums will never go with angels.you here all this crap about severums being really peacefull. my male was evil. it bite me loads and even drew blood a few times, he bullyed about the green terror in my avater, even though he was 2" larger, and also a male.
most of the people who i know have kept severums say their overly aggressive too.
severums will grow quicker than the angels so if you divide them theyl still get bigger and still see the angels as inferiors.
