hahah pilot, its a acrylic panel in between the window and seals on the lower part, with a door drilled into the panel. that white thing is just a sliding panel that goes over the door to lock it up.

Im thinking either fronts or tropheus, ive kept fronts for about a year and a half awhile back and loved it. The **** trophs are just so active and beastly. I can get 15 or a colony of em for cheap at the moment. We shall see, im waiting for this tangyakan eel.. he would love all that holy rock
