Female??

[krb1085]

Woke up this morning and it had dug a perfectly round hole in the rocks and is hanging around it. It is in a divided tank with another and I thought they were both males

males also dig pits, my big male moves about 50lbs of gravel in a day after every cleaning until he feels at home.

I would doubt that is a female but I've been wrong before

nice fish BTW

It's a male. Cichlids in general are known to dig pits in the gravel.
