Ok, I need some suggestions on what to do here and I am kind of a novice with angels. Currently in my 55 I have 2 angels and 2 blood parrots. They are doing fine together but I want to move the parrots to my 75 and do a nice looking angel tank with roughly 5 angles. The trouble is I didn't realize when I got my current angels how aggressive they can be. My angels are one large marble looking angel and a medium sized more natural looking one. I had 2 smaller ones already in the tank and the medium sized one keeps going after any other angel in the tank and harassing it until I have to remove it from the tank. I don't know if the 2 are pairing up but they have not bred or anything. Anyway, do you think there is any chance of getting my dream of 5 angels in my 55 or will these 2 never allow it? Or should I keep the 2 and add some other fish to fill out the tank? I don't really want my 55 to have just 2 angels in it. If I add 3 larger ones at once would it disperse the aggression? I love the beauty and personality of angelfish but I did not know how mean they can be!
