)Well I was not going to dive into this one at all but I have to say a few things.
We all keep fish because we think they are cool. I hope that we also care enough about the enviroment that we do things like buying from reputable LFS and getting as many frags as we can and enjoy watching them grow and make our tank look great. Doing a little reading about any live creature is important and should be done for everything be it fish or not (my wife is pregnant right now, and you think fish are expensive!).
All I am tring to say here is that enjoy the hobby try to make it fun for you and others and learn a bit on the way.
Now just to make sure that I am not going off topic
I did keep a manderin with very little live rock (30lbs in a 135gal tank) and it did very well and got very fat.
Everyone have a great DAY (PS I am also very slow at work and did not like the out come of the oilers game oh crap I am in the Calgary forum...well mabie the flames will make it next year
