I have had G bellcrossi for 19 months. Bought three in Jan '10, lost one a few weeks after and then bought another in Dec of '10.
All three have lived peacefully and are absolutely spectacular cichlids.
I honestly believe I have three that are the same sex. I have been looking for someone who has kept these to tell me if there is a difference between males and females.
I have plenty of pics and even several pics of each being vented.
The largest is about 6.5" (16.5cm)
A few pics...
