Having one will do just fine epecially if is introduced as one of the last fish you add to your tank, that way it won't be able to aquire the entire tank as it's territory.
Adding two in a small tank is not a good idea, even in a larger tank could be risky.Even tho it has no buddies to hang with, this type of fish either schools with many or is better own it's own. Adding a pair would be like grouping two fighting fish in the same tank, they would battle to the death.
And as I mentioned, I had one in my 27gl for four years along with two percs, a sixline, and two gobies and it never bothered any of the other fish.
