Severums are not African cichlids, but thats ok, a mod can move this to the New world cichlid section.
Remove the eggs as they are unlikely to get fertilised and the female will then have nothing to defend.
Are you sure the other is male? Could be another female, severums will lay eggs without a male around.
In the meantime if the aggression doesnt stop, you will need to move one of them to another tank or if you have no other tank, divide the tank with a divider.
What size tank is this?
? are you serious? you need to either rehome both sevs or invest in a 100 gallon or bigger . dont mean to sound blunt but those poor sevs need a bigger tank. tank size is certainly a faxctor in this agression^^ agreed, the minimum size tank for one severum is 75 gallon, the poor things must be squashed and stressed constantly.
