Generally speaking, if you ask for advice, you will get it whether you like it or not. Also, generalizing again, if you ask enough people, sooner or later you'll get the answer you want.
I asked the owner of the LFS, that I frequent, about putting a hipo in my "rich prick" 125 w/ my yellow tang. Keep in mind, store owner, he sell's fish for profit. He told me not to, because they would get too big and would get stressed over not having enough room.
Should I have gone to another store in order to get an opinion I wanted?
