blackwater tank cycling?

I was moving the orange tetra from the n.t. aquarium to the a. ipiranga aquarium since they were picking off too many frys and took this picture in case there is interest:

Random picture of a 100 (48x24) - well not random - had to do some work on it so spent an hour or so cleaning a few things - the only major change i think from last picture is i had 30 or so ruby tetra - they mostly hang out front but really object to the camera so they scattered as soon as i put the phone up there. Really nice tetra...
