Ok so I have one of these in my 180, but would like to add another. Is there any reason that I shouldn't? I done some reading and most say only one to a tank, but a few places have said its okay if there is enought distance and hiding places for the two so they won't compete for the same territory. Does anyone have first hand experience with more than one? Are ppl saying there can only be one to a tank because that has been a long standing myth or is there some practical knowledge for this? The reason I ask is I really like this fish and would love to have another?

One site said I couldn't have more than one unless they were a mated pair. I thought to myself, do they mean just like a "mated pair of clownfish" that are sold. Do they become a mated pair after a period of fighting?

I know so many questions, but I just don't understand some of the information that is out there regarding fish compatibility.

I guess if I get another I will have the "Goby Police" knocking at my door followed soon after by the tang police after they see the 6 tangs in my tank.

Thanks in advance and any info will help
