beautiful pair!! i was surprised when you said the sizes, your female looks like a monster! love that profile of her!!
my pair are both wild caught, ii put a big strawberry pot in the corner, covered it in pieces of wood to make a nice cave. and then put in a bunch of other much smaller fish. i had a 6 inch green terror, 2 3 inch green terrors, a 5 inch male festae and a 7 inch female festae. the only fish that was picked on and eventually taken out by my big male festae was the 6 inch green terror.
they spawned for me pretty fast, lost alot of the first spawn because i didnt get the other fish out in time. now the pair are all alone and i cant get them to stop spawning.
