This is a breeding pair plus one of the Tanganyikan cichlid Lamprologus ornatipinnis kigoma. They are small guys, no more than 2.5" long. The three were in a 20g long tank when the third was kicked out (fortunately into another tank). Apparently, I should have given them more hiding places or a bigger tank. They prefer shells over caves, once they are comfortable, they will spend most of the time in the open. I've had them two months and they have spawned at least three times.
