No worries garret, I didn't want to come off as rude either. I just wanted to be sure you would get the answers you were looking for.
Mono's are generally some of the easier cichla to sex and jayclarke hit the nail on the head with what has been my experience, sometimes the lump on the head doesn't show till 12" but at 10" generally is a good size that they start showing. Enjoy your new cichla!
