I am sorry you are being harassed and pushed around, there are so many people on forums who like to be the "best" and the "smartest" and so many that like to put down someone's opinion and/or experience. you are my friend, i am going to defend you, and it was pretty rude of them to put you down and use the "coo-coo" smilies, i hate it when someone acts like the best and smartest and picks on new users to try and prove they are the "best" and when they may think everyone is "inexperienced" and "stupid" they are wrong. everyone has their own experience and source of information, don't let anyone put you down. and i was not going to put a keyhole in my 55 gallon aquarium i picked up today, i don't even like them, they do not look like the best color, so i don't want a keyhole. and if aggression will be a problem, i'll probably just get a couple firemouths and a couple of convicts.
