Easy with the 10G brags, see my albums to see Red Terrors guarding eggs. The female is the brilliant orange and yellow one ( that the eggs came out of) . Identical to the 11.5 inch one in these pics. The male is also pictured, the one without the bright red, orange and yellow. Also pretty sure he is a male, considering the milt for the eggs came from his body. You can also see two females having a territory dispute, again, both are identical to the female in the pics here. But perhaps someone will dispute this, likely an armchair aquarist that had convicts breed once and spends a lot of time on line. Sigh.
226 tanks and 25 years in cichlids but still learn every day.
The festae is a female and a bargain.
