thanks Dex, I normally leave fish in the box for 2-4 days - depending on the reaction of my other fish. I waited longer with the Eightlines because our teenage Lineatus turned into demon spawn at the sight of them and it took him about 4 days to settle down. I kept them in the box for an additional 3 days and everything was fine when I released them.
As for the Earlei, yes, it is the awesome male from PIA. He will be here on Friday. We're a bit nervous, but very excited and feel like kids waiting for Christmas, LOL.
Good Luck with your C nahackyni pair... they are gorgeous fish!
