This one has spent the past few days working on a pit toward the right side of my aquarium, constantly picking up bits of gravel and spitting it out, pushing against a rock and stirring up debris with its tail end and flaring its gills like a male betta. Its developed a dark blue irridescent tint to its fins especially the anal fin.
The reason I ask about the sex is that both this one and its partner have pink bellies and not very pointy fins compared to my other Convicts. Not sure if this is part of male female behavior but the partner spends most of it's time away from the pit and is nearly twice the size of the pit protector. The one in the pit only eats if I drop food right above it and hasn't been feeding with the others since it started its project.
Perhaps my question is a common one but this is my first time keeping Cichlids so I'm doing the best I can to learn about their nuances.
