Its a con but the red belly doesn't for sure mean its a female. I've had a female convict that spawned twice and she never had a red belly. And i have also had males get reds and dark orange in there belly area. Either way its a good looking Convict.....
Nice looking female convict like everyone said. Get a male with no orange/ red on the belly and you will have babies for sure. The females tend to get blue and green on the fins also around spawning time. Most of the ones I have now and the ones in the past had this happen to them. Convicts are the rabbits of the fish world!
