Fish list for a 6g nano reef

[DragonForce]

Ok so I got my girlfriend a 6g nano with s stand for her appt. I was thinking about putting a pair of neon gobys in there. My question are; would a yellow and neon pair up or will they fight? or will they only pair up with their same kind? Thanks in advanced!

To the best of my knowledge, they'll only pair up with the same kind and will fight others that occupy the same space, look the same (ie: other gobies). Even adding a pair is iffy, unless you are sure that they are a mated pair. So be prepared to take one back if they start to fight. If it were my tank, I'd go with one goby.
