I noticed that one of the larger tilapia of mine is guarding a clay flower pot for dear life and is not eating. Could this be a female with eggs in her mouth? They are definitely doing the mating dance quite constantly. Although I haven't seen this particular fish doing it. He or she seems more interested in running everyone off than trying to entice someone over. It seems that all the flower pot's are spoken for. How funny, Anyways I just don't want to miss a female holding eggs. Thanks Guys, John
