Ha, Andrew! Keep your paws off my cichlids! Really, the dad is positively gorgeous. And he's gotten so much bigger since I got him -- only a little while ago.
This time, Dad is doing all the guarding of the eggs. I'm rarely seeing mom except at feeding time. This is different than last time. Dad seems less vigilant than last time, too, in terms of guard duty. But the tetras seem to remember the drill and are staying on their side of the tank. All quite fascinating to me . . .
