I have started a 72gal planted tank with small tetras, rasboras, assorted corydoras, ottocinclus and couple of ancistrus plecos. I thought that it would be ok to add juvie Angels to the tank so that they would grow up and be used to the smaller fish. There is ample shelter space in the plants for the small fish, but I don't want them to be hiding all the time. Will the angels get aggressive and dominate the other fish as they mature?
