Well I vented them. It was very obvious that I have a male and female. I've never vented a fish before but the difference was obvious. Thanks for all of your opinions and help. Since these two have been together for about a year, and have never spawned (as far as I know) what can I do to encourage them to do so. They have always been in tanks with other cichlids of the same size like oscars, and a 7" male jaguar and a large pleco. I have a 55 gallon running with no fish in it and fully cycled. Should I try putting them in that tank by themselves??? Thanks for any advice!!
