Breeding Angels

Hi All
I am in the process of setting up a new Aquarium (you may have seen my other topic in Discus)
My old tank has some Angels and other small fish. One of the angels has started laying eggs, The Angels cant be very old we bought them from peter Barrats about 9 months ago as small fish. The problem is they are bullying the other angel (See pic ) do I need to separate the fish and will it need treatment.

i would they get very protective about there eggs so the others could get hurt of even one of the parants

its also as to do with pecking order

the pecking order is normally sorted out before they breed only the boss and his chossen female will breed first

When i had angels that paired off and started breeding i would separate the breeding pairs into tanks of there own so they wouldn't pick on the other fish that way they would do what comes naturally and concentrate on producing.
Your angels have picked a territory and defending it, so obviously they are attacking anything that is within there boundary. It's entirely what you want to do, but personally i would put the breeding pair in a tank of there own.
