guy, Im no troll. dont speak to me like one. Im just letting people know what is going on outside the box. I realize that everyone here has a degree in marine biology and you are 29 and awesome, with an education, supposively in marine biology as well, but Im just cutting BS and saying things as fact. Dont get me wrong, I am amazed by my friends 75g, its really the best looking reef Ive ever seen. 5 of those fish are chromis, and I certainly wouldnt attempt to put that many fish in that tank if it was mine. but none of the fish seem unhappy. true, I never sat them down on a chair and had a heart to heart, but there all happy as far as I can tell. people want personal experiences on this site, not something most have just read out of a book. I just gave a personal experience that is unconventional. no need to jump down my throat. my 'facts' are just as valid as yours.
