Hey we're kind of new with the Cichlids and we have one acting alittle strange. He (though he could be a she) is the biggest and is aggresive. That we aren't shocked aout but today he started digging out a hole under one of the rocks. He's been at it all day. And if you look close at him him "thingy" seems to be swollen. Is our little Cichlid going to be a mommy?
