Green Severum

[kittycat12]

i got 2 green severums. one quite big and the other quite small. the big one chases the small one quite a bit. could one of them be female and male? or both males?

i've read that it's really hard to sex severums until they are older. does the bigger one have dark markings all over it's face or is it mostly uniform in color? Adult males usually have facial markings adult females don't but only adults develope these markings. there could be other reasons for the chasing but it could just be normal cichlid aggression. big guy beats up little guy...that kinda thing

How big are they? My severums often chase each other for a while, they have never bred though.
