Is it true you can't have two male geckos in the same tank?

You can't have two males in the tank or they will fight and then you'll end up with one very injured gecko or two very injured geckos.

Or one very dead gecko.

Sometimes they will get along when they're young...but once they reach maturity, they begin to fight for dominance, territory, and ladies. And those fights can get real ugly real quick.
